Earth Leakage Relays

Earth Leakage Relays

Making a design of the earth leakage protection with flexibility.

The earth leakage relays detect an earth leakage current for the single circuit.

Earth Leakage Relays - NV-ZBA

This kind of relay is an electrical self-holding type, called as compact-economic-type, and can serve to save a space.

Earth Leakage Relays - NV-ZBA

Earth Leakage Relays - NV-ZSA

This kind of relay is mechanical self-holding type, called as standard-type, and can combine with MCCBs or Contactors by two sets of output contacts.

Earth Leakage Relays - NV-ZSA

Earth Leakage Relays - NV-ZHA

This kind of relay is an electrical self-holding type, called as harmonic surge ready type, and is suitable to use in the inverter circuit can to have the active-filter and the DPDC circuit.
