Overcurrent Relay
SP 9270

The overcurrent relay is suitable for monitoring currents in three-phase and alternating current networks. When the switching point is exceeded, the relays changed their state after the time lapse. Due to the adjustable switching point, the relays are universally applicable. By means of the adjustable time delay, current peaks can be taken into account or faded out if required. Readiness for operation and overcurrent are each signaled via an LED.
