The IK 9272 and SK 9272 overcurrent relays are suitable for monitoring currents in three-phase and alternating current networks. If the switchting point is exceeded, the relays change state after the time has elapsed. The relays can be used universally thanks to the adjustable switching point. Using the adjustable time delay, current peaks can be taken into account or faded out if required. The operational readiness and switching status of the output relay are signalled via an LED.
