3 Pole 10mA/30mA/100mA/300mA Earth Leakage Circuit Breaker ELCB

Earth Leakage Circiut Breaker DZ47LE(ELCB)
Scope of application
Earth Leakage Circuit Breaker(ELCB)TLYB1LE-63 is usedfor the protection against electrical leakage in the circuit of 50HZ or 60HZ, rated voltage single-phase 240V ratedd current up to 63A. When somebody 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 protecting the personal safety and precenting the equipment from the fault resulted from 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.
The products conforms to IEC61009-1 and GB16917.1 standard.
