NPM800

Dedicated motor protection

Provides protection for medium-voltage motors and high-power lowvoltage motors.

Our NPM800 relay analyses the currents drawn by the motor during the starting, re-acceleration, and normal operating phases. It also supervises the proper functioning of the circuit breaker and its tripping circuit.
