TKM8L moulded case circuit breaker with residual current protection Rated insulation voltage is 800V. It applies to circuit of AC 50Hz, rated working voltage 400V and rated working current up to 630A for infrequent switch over and infrequent start of motor. With overload, short circuit and under-voltage protection, it can protect circuits and power-supply equip-ment from damage; can also be used for protect from any potential fire hazard caused by long existing earthing fault which can not be detected by over-current protection. .
