What is a Shunt Trip Breaker?

If the circuit breaker trips it finds faults condition and automatically shuts off the current flow to prevent the circuit from overheating.  The shunt trip breaker is an optional device for a circuit breaker that helps to trip the breaker remotely in any instant or automatically in case of surge saving any damage and instrument damage.

There are 2 main types of shunt trip breakers first one is manual and the second one is automatic.

Manual witches help to off the breaker externally with the use of the remote button. Automatic switch off power when detecting surges from the external power supply.

 How Does a Shunt Trip Breaker Work?

Normally the current passes through the circuit breaker. But if these currents become high surges, the larger surge of power changes the electromagnet below the breaker switch, tripping the cutting power and switch.

The shunt trip breaker offers extra techniques to charge the electromagnet and trip switch, helping remote or automatic power shutoff. Some hunt trips are connected to an external power supply.  When power surges get that source, signal flow from shunt trip to the breaker, mechanical cutting power.

The shunt trip can make a connection with the remote switch outside the building. Pushing the button on the switch sends a surge through shunt trip wiring and off the power.

A shunt trip breaker comes with differnt components:

  • The frame of the shunt trip circuit breaker works as an external protective housing and covers all inner components. it is made with the use of durable materials like metallic that help to avoid damage to sensitive inner circuits.
  • Contacts are the main part of the circuit breaker that carries electric current. in a shunt trip circuit breaker, there are two types of contacts, main contacts, and auxiliary contacts. The main contact is used for normal power transmission, and auxiliary contacts are used for connecting the external control system

Operating Mechanism:

  • The working phenomena in shunt trip circuit breakers help to open and close contacts. it comes with latch releases and trip units. The latch releases are used for maintaining contacts in the closed position until the trip mechanism works. The trip unit detects abnormal electrical conditions and starts the tripping process.

Electromagnet:

  • At the core of the shunt trip circuit breaker electromagnet exists, which is important for working. If the external signal gets, the electromagnet activates and produces a magnetic field. This field work on latch releases resulted to open circuit breaker contacts.
  • It is the main part of the shunt trip breaker that operates uniformly with an electromagnet. its working is to get an external signal and convert into electrical energy. this energy is used to producing the field needed for tripping breaker.

Why Are Shunt Trip Breakers Important?

irrespective optional nature of the shunt trip breaker, it can be an important safety instrument in a power system. As a result, many engineers use this breaker as a layer of security since they save damage during power surges.

This breaker is good for many fonts but it’s commonly used during fire. By turning off power if a fire breaks out, the electrical hazard is no main risk. Some connections shunt trip to smoke alarm in homes, for power automatically off when detector trigger alarm. It not be good option, since in some conditions smoke alarm gets off due to steam from the shower of smoke from the kitchen

  • Data centers come with computing devices and sensitive data. Shunt trip breakers are used to protect these facilities from electrical hazards.

 Advantages of Shunt Trip Breakers

  • The main benefit of a shunt breaker is that it can remotely shut off in case of any fault. It quickly works and disconnects power in fire which helps to avoid damage in the home and protects people.
  • These devices also increase safety levels and security by automating off power to the circuit if there is any fault. it helps to save electrical fires and any other damage.
  • The shunt breaker is easily connected and confined with a power system, so it is easy to install the device in the building.
  • The shunt breaker is a less cost solution for safety measures in buildings and industries. it is less costly to buy and connect and helps to save homes and buildings in the result of high fault.
  • Shunt breakers support many electrical systems and devices so it is versatile devices that are used for the protection of circuits.

 Comparison with Other Circuit Protection Devices

Shunt trip breakers vs. standard circuit breakers.

The basic difference between shunt trip breakers and regular circuit breakers is their function. Regular breakers are manually operated and based on a user-to-flip switch if requried or on current overloading that triggers the unlatching process.

While shunt trip breaker provdies more layers of controls. it can be triggered remotely with the use of a switch or automated system. These features allow them to immediately off power in case of fault.

Shunt trip breakers vs. ground fault circuit interrupters (GFCIs)

GFCI monitors equality between L1 and L2, if there is more than predefined difference in trips. The shunt breaker is a combination type device that combines in regular breaker with its regular function trip it has a remote control to trip breaker.

Ground fault breakers monitor current on neutral wire flowing back to the neutral bar, the four to six-milliampere different trip breakers, and shunt trip breakers can tripled remotely from other switches or points. In industrial uses, it is used to shut off in emergency condtion, when access to an electrical panel is difficult.

what is a shunt trip breaker

What is a shunt trip breaker? Does it add protection to your electrical system?

The shunt trip breaker is a combination of the shunt trip accessory and the main circuit breaker. This installs on the main breaker to add protection to your electrical system. This adds security to your electrical system as it manually or automatically cuts the electric supply in your circuit.

This accessory can help prevent short circuits and avoid electrical damage should a disaster occur in your home.

Let me tell you more about the shunt trip breaker to help you decide if you need additional protection for your electrical system.

What is Shunt Trip Breaker and How Does It Work

Where are shunt trip breakers most used, how to install a shunt trip accessory to the breaker.

shunt-trip-relay

You should know that shunt trip breakers are different from GFCI circuit breakers.

The GFCI circuit breaker contains one big white tail wire for neutral connections only. It cannot be connected to any control package because the GFCI circuit breaker is solely designed to detect a sudden electrical surge. It has no other purpose but to cut power in case of a short.

Meanwhile, the shunt trip breaker wiring comprises two wires. One connected to the ground, and another to a control system. The control system can be connected to a sensor or to a manual switch. When activated, the shunt trip accessory will cause the main breaker to trip.

For example, if you install a shunt trip with a smoke detector, it will activate and cut off the power should the smoke sensor trigger. It can also be installed with a remote switch , allowing you to trip your breaker manually.

It is crucial to know the difference between a regular circuit breaker and a circuit breaker installed with shunt trip accessories.

shunt-trip-definition

The shunt trip definition means that it is a way to cut off electrical power through other sensors, not just via thermal activation. Since this is an optional accessory for a circuit breaker, it is not required for a home electrical system.

However, it is recommended for added safety. This is especially true if you’re working with industrial machinery. Furthermore, you can use it as a manual emergency switch to shut down your main breaker.

Before installing a shunt trip, consider its cost and your existing system. You may need to change the breaker panel  and circuit breakers, especially if it is not compatible with shunt trips. You may also need a new line to connect the remote emergency switch to your breaker box.

Generally, most commercial kitchens, elevators, and offices have this shunt trip breaker because it is required. Commercial kitchens use this device in compliance with ANSI/ASME CSD-1, while elevators and escalators comply with ASME A17.1. These codes refer to the controls and safety standards provided by ASME’s.

This question is a topic of discussion among Reddit members as well. Join the conversation here:

Mostly, installing a shunt trip relay requires that the breaker and the shunt be from the same maker. Also, not all breaker models are compatible with this accessory.

Once you’re sure that your system can take a shunt trip accessory, installation is pretty much straightforward. You can watch this video by Aaron CBIONE for some tutorials.

Note: Every circuit breaker comes with different instructions. It would depend on the brand and model of the breaker .

However, the critical part of every installation is that you need to connect the shunt to your sensor. You may need a shunt trip breaker diagram as a reference to ensure correct installation.

Also, check the brand and model of your breaker before proceeding with the installation. Some makers only allow a factory install of the shunt trip and other accessories. DIY installation may void the warranty of your breakers. It’s best to read up on the manual or consult an electrical professional before making any changes.

What is a shunt trip breaker? The shunt trip is an optional accessory for a circuit breaker for added protection to your system. It is designed to connect to a secondary sensor. It will trip the breaker automatically if the sensor is triggered. It can also be activated via a remote switch that you can install.

Do you think that a circuit breaker is enough to protect your investment? Or do you want an additional layer of protection for your electrical circuit? If you’re not decided yet, reach out to me in the comments section below, and I will be happy to help you.

Shunt Trip Parts In Stock for Remote Tripping Your Circuit Breakers

Remotely trip and disconnect power to a specific circuit, safely and remotely trip circuit breakers.

A shunt trip is an electrical circuit’s equivalent of a heroic maneuver. Consider a circuit breaker to be a guard for your electrical system. Its purpose is to keep things from going crazy if there is too much power present.

Enter the shunt trip, which functions similarly to the guard’s remote control. When you push a button on this remote, a particular coil inside it becomes energized and generates a magnetic field. This magnetic field communicates with the circuit breaker and nudges it, saying, “Hey, time to take a break!”

The circuit breaker receives the signal and says, “Alrighty, shutting down now!” It just opens its connections and cuts off the electricity flow. This comes in handy when you need to rapidly turn off the power from a distance. Consider it a safety switch that you can activate even if you aren’t directly next to the breaker.

In other words, a shunt trip is a remote-controlled means to cause a circuit breaker to trip by utilizing a magnetic magic trick. It’s useful for keeping things secure without having to go around flipping switches.

  13. Shunt trip voltage

    Applying voltage to the shunt-trip coil causes the breaker to trip. That voltage needs to be momentary because you can burn up the shunt-trip coil. So whatever scheme you use to trip the breaker, the voltage cannot be sustained after the breaker trips hence the recommendation to use the breaker itself to supply the control voltage.
