KLR series leakage protection relay cooperates with KCT leakage transformer. When the leakage current reaches the set value, the relay acts. Through shunt/undervoltage release, low voltage circuit breakers or AC contactors of various specifications, such as UKM32, cut off power supply to protect personal or equipment safety.
KLR523 has 25 selectable sensitivity setting values: 30mA to 30A, 9 selectable delay values: 0 ms to 3 s, leakage level indicator, delayed start indicator, tripping indicator, leakage/virtual connection/disconnection detection of current transformer, and extremely strong anti-interference capability.
KLR523E also has 50% fault pre alarm contact, remote test and remote reset functions.
