DZ47LE Earth Leakage Circuit Breaker

DZ47LE (C45LE) earth leakage circuit breaker is used for the protection, against electrical leakage in the circuit of 50Hz or 60Hz, rated voltage singe-phase 240V, 3 phase 415V, rated current up to 60A.When some body gets an electric shock or the residual current of the circuit exceeds the fixed value, the ELCB can cut off the power within the time of 0.1s automatically to protect the personal safety and preventing the equipment from the fault resulted by the residual current. With this function, the ELCB can protect the circuit against overload and short circuit or can be used for the unfrequent switchover of the circuit under normal conditions. lt conforms to IEC1009 standard.

YZW15 Universal Air Circuit Breaker

YZW15(DW15)series universal auto air circuit breakers(herein after referred to as the breakers)are suitably used in AC 50Hz,rated current up to 4000A and rated working voltage up to 1140V(using frame level rated current 630A and below)and 380V (using frame level rated current 1000A and over)power distributing systems for power distribution and protection fo power supply circuit and power apparatus from overload, under voltage and short circuit.

YZW15 Universal Air Circuit Breaker
YZW17 Universal Air Circuit Breaker

This series air circuit breakers are suitable used in AC50/60Hz, 380V distributing systems with normal current up to 4000A for power distribution and overload, under-voltage and short-circuit protection of apparatus and circuit.Under normal conditions the breakers are used for infrequent switchover of circuits. The breakers with rated current below 1 250A used in 50/60Hz, 380V systems can protect motors form overload and short circuit, and actuate motors unfrequently under normal conditions.
