NPIHD800R

Directional overcurrent earth fault protection

NPIHD800R (R2 case) is dedicated to the refurbishment of 7000 series of earth fault overcurrent and directional CEE 7000 relay.

Our NPIHD800Rsupervises in particular the phase to earth faults and the good operation of the circuit breaker and its trip circuit.

CEE 7000 R case compatible

Minimises retrofitting costs

Reduces re-commissioning time
