It injects a small, supervised current through the trip circuit to verify continuity even when the circuit breaker is in the open or closed position. If the relay detects an interruption—whether caused by a broken wire, a blown fuse, or a faulty auxiliary contact—it immediately changes the state of its internal output relay to alert the SCADA or alarm system. This proactive monitoring eliminates \"blind spots\" in the protection chain, ensuring that when a protection relay commands a trip, the hardware is electrically capable of executing it.\u003c\/p\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":44096068190307,"sku":"SPER1C1","price":180.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0549\/2775\/3315\/files\/292.png?v=1775032526","url":"https:\/\/precisemodule.com\/products\/abb-sper1c1-trip-circuit-supervision-relay","provider":"Precise Module Ltd.","version":"1.0","type":"link"}
