S MOULDED CASE CIRCUIT BREAKER

Application
S series Moulded Case Circuit Breaker if suitable for short circuit & overrload protection in the circuit of 690VAC 50/60Hz, rated current from 12.5 to 630A Its rated insulation voltage is 690V. It can make & break non-frequentiy the circuit in the normal conditions. It takes protective effect when mouse cage motors non-frquent start, breaking off working and protecting overload, short circuit and lacking voltage. It conforms to IEC60947-2
