KNL5 series Residual current circuit breaker(without over-current protection) is suitable for the line of AC 50/60Hz, voltage 240V(2pole)/415V(4pole), rated current up to 63A. When there is human electricity shock or if the leakage current of the line exceeds the prescribed value, it will cut off the power rapidly to protect human safety and prevent the accident due to the current leakage. It can be used as infrequent changeover of 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.
