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.
Earth Leakage Relays NV-Z
This kind of relay is an electrical self-holding type, called as compact-economic-type, and can serve to save a space.
The Earth Leakage Relays are classified into the following types,
･ NV-ZBA (small-size economical product)
･ NV-ZSA (general-use product)
･ NV-ZHA (applicable to higher harmonics and surge)
･ NV-ZLA (applicable to higher harmonics and surge)
