DOLD 0063460: SK9173.11/230 AC230V 0,7UN4% Undervoltage Relay, Single-Phase

The IK 9173 and SK 9173 voltage relays in the VARIMETER series monitor AC voltage networks for undervoltage. The measurement is very simple and does not require a lot of wiring, as no separate auxiliary voltage is required. Early detection of impending failures and preventive maintenance prevent costly damage and, as a user, you benefit from the operational reliablility and high availability of your system.
