Earth Leakage Relays

The Earth Leakage Relays combined with ZCT can detect and output signal when earth leakage is occurred.

Various types of relays and ZCTs are prepared.
High level of earth leakage protection is available combined with MCCBs or external circuit.

  1. 1.We have the compatibility type with which relay part and ZCT part are freely combined.
  2. 2.In addition to the standard type, we also have higher harmonics wave type and surge type.
  3. 3.For Earth Leakage Circuit Breakers, when combined with No-Fuse circuit breakers you can break Earth-fault circuits.

Some products are regionally specific; for up to date sales availability, please check your local web page.
