NPUH800R

Earth fault voltage protection

Our NPUH800R (R2 case) is dedicated to the refurbishment of 7000 series relays.

It monitors the zero-sequence voltage of three-phase networks with isolated or high impedance earthed neutral.

It protects against phase to phase and phase to earth faults and ensures the proper functioning of the circuit breaker and its tripping circuit.
