Carlo Gavazzi DPB01CM48N 3 Phase Voltage Monitoring Relay, Over / Under Voltage, Phase Loss, 380 to 480 VAC

The Carlo Gavazzi DPB01CM48N is a 3 phase voltage monitoring relay that protects motors and equipment from phase loss, over voltage and under voltage. The over and under voltage limits and the alarm delay are set on front dials, and the relay is powered from the monitored supply, so no separate auxiliary supply is needed. It suits 380 to 480 VAC systems, with or without neutral.
