Electrical contacts are electrically regulated switches that complete or interrupt a circuit affecting an electrical current, which carry higher current loads and are structured to be directly connected to high voltage feeds.
VCB contact come in various sizes and forms, from small to very large, depending on usage and voltage requirements. A circuit breaker contact has three fundamental components, a stationary contact, a movable contact, and an operating coil. Once power is sent to the control coil, it creates an electromagnetic current and forces the movable contact arm to open or close to interrupt or complete the circuit.
