Interrupter Contact Set

An interrupter contact set, also known as an interrupter switch or interrupter assembly, is a component used in electrical circuit breakers and switches. It is responsible for interrupting or breaking the flow of electrical current when the circuit is overloaded or a fault occurs.

The interrupter contact set consists of two contact points, typically made of copper or silver, that are designed to make and break the electrical connection. When the circuit breaker is closed, the contacts are in contact with each other, allowing the current to flow through the circuit. However, when an overload or fault is detected, the contacts are quickly separated, creating an air gap that interrupts the current flow.

The interrupter contact set is designed to handle high voltages and currents, and it must be able to withstand the arcing that occurs when the contacts separate. Arcing is the electrical discharge that happens when the current is interrupted, and it can generate heat and potentially damage the contacts. To prevent this, interrupter contact sets are often designed with special materials and shapes to minimize arcing and ensure reliable operation.

In summary, an interrupter contact set is a crucial component in electrical circuit breakers and switches that is responsible for interrupting the flow of electrical current when necessary to protect the circuit and prevent damage or hazards.
