NPI800R

Phase and residual current protection

Designed to replace our CEE 7000 overcurrent phase and earth relays, while remaining compatible with the R-format mounting base of the CEE 7000 range.

The NPI800R monitors, in particular, phase-to-phase and phase-to-earth faults, reverse currents, the thermal state of equipment, as well as the proper operation of the circuit-breaker and its tripping circuit.”
