NPI800

Overcurrent protection

Provides phase and earth overcurrent protection for medium and high voltage electrical networks.

Our NPI800 monitors phase to phase and phase to earth faults, negative sequence currents, reverse currents, the thermal state of the protected device, and ensures proper operation of the circuit breaker and its tripping circuit.
