A shunt trip breaker is an important device that you can use to control power supply to various electrical devices. The breaker is made up of a number of components, including a shunt trip mechanism that is responsible for opening the circuit automatically whenever there is an overload or fault. In this article, we will look at a wiring diagram for shunt trip breakers from Schneider Electric, one of the leading manufacturers of electrical equipment in the world.
What is a Shunt Trip Breaker?
A shunt trip breaker is a breaker that has a shunt trip mechanism added to it. The shunt trip mechanism is made up of an electromagnet that is used to trip the breaker whenever it receives a signal. This signal can come from a variety of sources, including an external switch, a fire alarm system, or a manual trigger.
The shunt trip mechanism is designed to open the circuit automatically whenever there is an overload or a fault in the system. This helps to prevent electrical fires and other hazards that can result from electrical faults.
How Does a Shunt Trip Breaker Work?
A shunt trip breaker works by opening the circuit automatically whenever it receives a signal from the shunt trip mechanism. The shunt trip mechanism is designed to trip the breaker whenever it detects an overload or fault in the system.
Once the shunt trip mechanism has been triggered, it sends a signal to the breaker, which opens the circuit and cuts off power to the electrical device. This helps to prevent electrical fires and other hazards that can result from electrical faults.
What is a Wiring Diagram?
A wiring diagram is a diagram that shows how electrical devices are connected in a circuit. Wiring diagrams are used by electricians and other professionals to help them understand how electrical devices are wired together.
A wiring diagram typically includes information about the components used in the circuit, the connections between these components, and the power supply that is used to power the circuit.
