Zero-sequence Overvoltage NPUH800 / R
NPUH800 / NPUH800R relays protect three-phase networks with isolated or high impedance earthed
neutrals against earth-faults.
ANSI functions:
59N / 86 / 74TC
These relays are part of the NP800 range, offering multi-function protection and communication via Modbus (RS485) or Modbus TCP (Ethernet). A full brochure is available on the NP800 range page
