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-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-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.
Earth Leakage Relays - NV-ZLA
This kind of relay is an mechanical 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.
