NPM800RE

Motor protection

Our NPM800RE (R3 case) is dedicated to the refurbishment of 7000 series of CEE 7000 motor protection relays.

Our NPM800RE provides protection for medium-voltage motors and high-power lowvoltage motors.

This multifunction 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.

The NPM800RE has additional DI and DO compared to our NPM800R.
