Low Voltage ComponentsDisconnect switches generally refer to high voltage disconnect switches with 1Kv or above rated voltage. In the circuit, disconnect switches have the function of isolation. They are the most commonly used switches among all high voltage switching apparatus. Its operating principle and structure are simpler. However, as they have a large usage amount, a high operational reliability is required, which has great influence on the design, building and safe operation of electric power substations and electric power plants. The disconnecting link has no arc extinction ability, so it only can seperate and close circuits when there is no load current.
Low Voltage Circuit BreakerMCB (Miniature circuit breaker) is a thermal-magnetic breaker whose rated current is less than 100A. Normally, its trip characteristics are nonadjustable.
