Power distribution equipment Main electrical components
Circuit breaker: used for circuit on, off, overload and short circuit protection, including frame circuit breaker, molded case circuit breaker and miniature circuit breaker, etc. contactor: it is used to frequently turn on and break the main circuit, and control the start and stop of electrical equipment such as motors. relay: used for the protection and control of control circuits, including time relays, thermal relays, intermediate relays, etc. fuse: it is used for short circuit protection of circuits. when the current exceeds the rated value, it blows and cuts off the circuit. transformers: including current transformers and voltage transformers, which are used for measurement and protection, and convert large current and high voltage into small current and low voltage for measuring instruments and protection devices. instruments: including voltmeter, ammeter, power meter, frequency meter, power factor meter, etc., which are used to monitor the operating parameters of the power system. indicator lights and buttons: for displaying device status and operational controls.
