KNL5-63/63H Residual Current Circuit Breaker With 50/60Hz

KNL5-63/63H Residual Current Circuit Breaker With 50/60Hz

KNL5 series Residual current circuit breaker(without over-current protection)is suitable for the line ofAC 50/60Hz,voltage 240V(2pole)/415V(4pole),rated curent up to 63A.

When there is human electricity shock orif the leakage current of theline exceeds the prescribed value,it wil cut offthe power rapidly to protect human safety and prevent the accident due to the current leakage.

It can be used as infrequent changeoverof the line in normal situation.It is applicable to industrial site,commercial site,tall building and civil house.

It complies with standard of IEC/EN61008-1 and GB16916.1.
