Current sensor relays from Grainger protect heavy machinery from sudden current changes. Current sensors detect voltage changes and respond accordingly. The current sensing relay switches power on or off when overloads, undercurrents and lamp loads occur. Find an A/C current sensor relay or selectable current relay here.Close
