A breaker shunt trip wiring diagram is a diagram that explains how to wire a circuit breaker with a shunt trip. This type of wiring is used when a circuit breaker needs to be triggered by an external switch, such as when a fire alarm system is connected to the circuit breaker. By understanding the diagram, it is possible to correctly wire the circuit breaker and ensure the safety of the system.
Parts of a Breaker Shunt Trip Wiring Diagram
The breaker shunt trip wiring diagram consists of three main parts. The first part is the power source, which is usually a high-voltage power supply. Next, there is a circuit breaker which can be either an individual breaker or a multi-pole breaker. Lastly, there is the shunt trip, an external switch that is used to trigger the circuit breaker when activated.
Wiring the Circuit Breaker with a Shunt Trip
Once the power source, circuit breaker, and shunt trip are all identified, the next step is to wire the circuit breaker with the shunt trip. This is done by connecting the shunt trip to the breaker’s trip coil. The trip coil is what triggers the circuit breaker to open when the shunt trip is activated. The shunt trip should also be connected to the circuit breaker’s neutral line. Once the wiring is complete, the circuit breaker can be tested to ensure that the shunt trip is working properly.
Benefits of Installing a Breaker Shunt Trip
Installing a breaker shunt trip is beneficial for many reasons. Not only does it provide an additional layer of safety for the system, but it can also help reduce energy costs. By having the circuit breaker triggered by an external switch, it prevents the circuit breaker from being constantly on, which can save energy and money. In addition, the circuit breaker will be triggered when necessary, providing an extra layer of protection for the system.
Conclusion
Understanding the breaker shunt trip wiring diagram is essential for correctly wiring a circuit breaker with a shunt trip. This type of wiring is used when an external switch is required to trigger the circuit breaker, such as in the case of a fire alarm system. It is important to ensure that all the parts are correctly wired in order to provide the best level of safety and energy efficiency.
