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.
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.
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.

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.

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 fo 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.

Table of Contents
What is a shunt trip breaker?
A shunt trip device is an optional accessory for breakers that allows you to trip a circuit breaker with a remote, or automatically trip the switch during electrical surge or short circuit .
Shunt trip breakers are mostly used in commercial and industrial applications to enhance safety and protection of electrical appliances.
Types of shunt trip breakers
There are two main types of shunt trip circuit breakers they include.
- Automatic shunt trip breakers: These breakers trip automatically when they detect an electrical fault such as an overcurrent or a fire alarm.
- Manual shunt trip breakers: These breakers are tripped manually by pressing the remote button.
How the shunt trip circuit breakers work
A shunt trip breaker works like other circuit breakers . However, it comes with a solenoid coil which is connected to a separate control circuit.
When the control circuit is energized due to electrical fault or overload, it creates a magnetic field around the solenoid coil, which pulls a plunger inward.
This plunger is connected to the tripping mechanism of the circuit breaker. So when it is pulled inward, it trips the breaker and cuts off the power source.
Alternatively, a shunt trip breaker can also work with a remote control so you can trip the breaker remotely when there are electrical hazards
Where are shunt trips required
Shunt trip circuit breakers are used in various applications such as
- Industrial machines to protect it from damages that may arise from electrical faults.
- Fire protection systems to automatically shut off electrical power in the event of a fire outbreak.
- in commercial buildings for additional protection against electrical damage.
- hospitals and healthcare facilities to protect hospital equipment from electrical damage.
Advantages of using a shunt trip breaker
There are several advantages to using a shunt trip devices, these include:
- Enhanced Safety: It provides an additional layer of safety by quickly tripping the main breaker in the event of a fault or overload, preventing potential damage to electrical equipment.
- Remote tripping capability: A shunt trip breaker usually comes with a remote control to enable you to turn off the breaker at any needed time.
- Protection of sensitive equipment: It can help protect sensitive electrical equipment from power surges caused by overload or faults, ensuring the durability of the equipment.
Shunt trip breaker wiring
Before you wire a shunt trip, there are some things you will need to know.
Shunt trip is an accessory and is not compatible with all breakers. Some breakers come with an in-built shunt trip, others require specific models, or to be installed in the factory. Therefore, it is necessary that you evaluate all these before the wiring .
If the breaker is compatible with the shunt trip device, you can then follow this wiring diagram to install it.
Based on the MCCB shunt trip breaker wiring diagram above, the 3-phase 4-wire system from supply is connected to the mccb breaker .
The neutral wire is connected to the shunt coil, and the control line wires to the EPO button.
Difference between a shunt breaker and a GFCI
A shunt trip and a ground fault circuit interrupters (GFCI ) are both electrical devices , however, they are designed to work in different ways and for different purposes.
Below are their major differences.
