Low Voltage KNLE1-63P/100P Leakage Circuit Breaker

Low Voltage KNLE1-63P/100P Leakage Circuit Breaker

KNLE1-63P/100P series leakage breaker is suitable for the leakage protection of the line ofAC 50/60Hz,rated voltage single phase 240V,threephase240/415Vand below,rated curent up to 100A.

When thereishuman electiciyshock oriftheleakage current of the line exceeds the prescrbedvalue,it will utomatically cut offthe power within 0.1s to protect human safety and prevent the acident due to the current leakage.

KNLE1 series leakage breaker can protect against overload and short-circui.It can be used to protecthe line from being overloaded andshort-circuited as well as infrequent changeover of the line in normal situation.

It complies with standard of IEC/EN6100-1 and GB16917.1.
