Not all circuit breakers accept shunt trip accessories. In fact, different breakers may require specific shunt trip accessory models. Some breakers also have a built-in shunt trip accessory—all you need is to wire and connect to your circuit to activate it.

Furthermore, some circuit breakers are only intended to have shunt trip accessories installed from the factory. So, before purchasing a shunt trip accessory, it’s highly recommended that you review what make and model of breaker you have. That way, you know what your options are before installation.

If you have a compatible system, you still need a shunt trip circuit breaker wiring diagram to ensure correct installation. However, do not just download any chart from the internet. For example, if you have a Square D branded circuit breaker, you need a Square D shunt trip breaker wiring diagram.

Before beginning installation, ensure that everything you need is within your reach. Also, always think of safety first!

Step-By-Step Guide to Wire a Shunt Trip Breaker Wiring Diagram

First, install the shunt trip accessory to your breaker. This procedure is pretty straightforward. Open your circuit breaker using a small flathead screw. Insert the insulator into its right place, and feed the wires in the holes near the shunt trip. Secure the shunt trip to its location, and put the cover back to the circuit breaker. And you’re done!

You can watch this video by Aaron CBIONE for a video guide on installing a shunt trip to the circuit breaker.

Note: Different makers have different installation processes. It’s best to refer to the manual guide provided in your circuit breaker.

Once the shunt trip accessory is connected to your circuit breaker, you need to connect it to your panel board as the main circuit breaker. Before installing this device, ensure that your system has no power.

If you’re not sure, it’s best to consult a professional electrician to avoid any accidents.

Once ready, open your panel board using your flathead screwdriver and plug in your shunt trip circuit breaker into the main power supply. Connect the mainline and the supply wire to the circuit breaker, then proceed to the next step.

Before wiring your shunt trip breaker to your safety control system or switch, you need first to understand its wiring diagram. This is a crucial part of the installation—that’s why you can’t skip it and need to be more careful with it.

Take a look at this recognizable wiring diagram made by Sikandar Haidar of Electriconline4u as a typical example.

Note: This sample diagram is simple and easy to follow. However, different systems may require other designs. Refer to the charts provided with the shunt trip, safety control system, or switch before starting. If you’re unsure, it’s best to consult a professional.

Using the sample above, connect one wire of the shunt trip to the neutral connection, then attach the other wire to the kill switch. Place a wire on the other side of the terminal of the kill switch through the supply connection.

With this, you now have a kill switch you can use to trip your electrical system’s main breaker quickly.

Pro Tip: Place the kill switch in an accessible area like near an emergency exit, so if a problem occurs, you can easily access it.

After installation, turn on or reconnect the power source to your main breaker panel . Flip the shunt trip circuit breaker on to begin testing your work.

To test your installation, press the kill switch. The shunt trip circuit breaker should immediately trip after pressing the kill switch. If it is not tripped, then there is something wrong with your installation.

Although not a requirement, having a shunt trip breaker in your residence provides an additional layer of safety. This is an excellent option if you have sensors in your building, like smoke detectors or fire alarms.

In case of emergencies, like flooding or sprinkler activation, you can also cut the power source by hitting the kill switch. This can prevent any shorts or accidental electrocutions because no power is supplied to your outlets.

So, what do you think of the installation process? Is it easy enough to DIY? Would you do this on your own? Remember to follow how to wire a shunt trip breaker wiring diagram. If you have any questions, feel free to reach out in the comments below.

A shunt trip breaker works by tripping the breaker when it receives a signal from an external device, such as a fire alarm or security system. This helps to prevent dangerous electrical fires or other hazards. When an emergency occurs, the external device sends a signal to the breaker, which causes the breaker to trip and open the circuit, interrupting the flow of electricity and preventing power from reaching the circuit, allowing for a quick and easy power disconnection.

Types of Shunt Trip Breakers

Now that you know the answer to "How does a shunt trip breaker work", it's time to discover about the two main types of shunt trip breakers.

• Manual Shunt Trip Breaker: This type of trip breaker requires manual intervention to reset the breaker after it has been tripped, meaning someone must physically go to the breaker and reset it after an emergency situation. This breaker is typically used in smaller residential buildings or situations where a dedicated staff member is available to reset the breaker.
• Automatic Shunt Trip Breaker: This type of breaker can automatically reset itself after being tripped and is typically used in larger buildings or in situations where there is not always someone available to reset the breaker. These breakers are often connected to fire alarm systems or other emergency management systems for auto-reset.

When is a Shunt Trip Breaker Required?

If you're wondering when is a shunt trip breaker required, know that it is required in any electrical system where there is a need to quickly and easily shut off power in the event of an emergency, such as a fire or security breach. Continue reading as we describe the importance of using shunt trip breakers and how to figure out which one you need to use for your building or facility.

The Importance of Using a Shunt Trip Breaker

• Shunt trip breakers automatically shut off power in emergencies.
• They prevent dangerous electrical fires and other hazards.
• They allow for quick and easy power disconnection in emergencies.
• They are easy to install and cost-effective solutions for increasing safety.
• They can be connected to fire alarm and emergency management systems.
• They ensure that the electrical system is in compliance with safety regulations.
• They are a versatile and practical solution for increasing safety in various settings.

Which Type of Shunt Trip Breaker to Use?

A manual breaker may be appropriate for a smaller building or in situations with a dedicated staff member available to reset the breaker, while an automatic breaker may be more appropriate for a larger building or in situations where someone is not always available to reset the breaker. Another option to consider is the use of a shunt trip relay, which can be used to trigger a shunt trip breaker remotely. These relays are typically connected to fire alarm systems or other emergency management systems and can send a signal to the breaker to trip it when an emergency occurs.

Shunt Trip Breaker Wiring Diagram

If you're wondering how to wire a shunt trip breaker, know that wiring can seem like a daunting task, but with the right knowledge and tools, it can be done relatively easily. Follow the steps below:

• Obtain a "How to wire a shunt trip breaker wiring diagram." (Check above).
• Gather necessary tools and materials such as wire strippers, nuts, and a voltage tester.
• Disconnect the power and wire the shunt breaker according to the instructions provided.
• Reconnect power to the circuit and test the breaker to ensure it works properly.

It is important to pay close attention to the diagram and follow the instructions carefully. This will ensure that the breaker is wired correctly and functions. Once the wiring is complete, you can reconnect the power to the circuit and test the breaker to ensure that it is working properly. It is always better to consult with a professional if you aren't confident about the wiring process. 

What Does a Shunt Trip Breaker Do?

We hope by now you know what does a shunt trip breaker do, but here's a recap: a shunt trip breaker is a specialized circuit breaker that protects your house electrical systems from damage or hazards in emergencies. It works by tripping the breaker when it receives a signal from an external device, such as a fire alarm or security system, preventing dangerous electrical fires or other regular hazards.
