Syrelec LIR-T Relay

The Syrelec LIR-T current control relay (a current monitoring relay) provides AC current sensing and protective switching for industrial power monitoring and automation systems. It operates from 110 VAC with SPDT contacts rated at 10 A, a trip range of 0.05–10 A AC, and a 0.1–10 second delay, and it mounts in a plug‑in socket with a relay contact output for use with motors, pumps, compressors, and control panels. Commonly installed in motor control centers, control panels, conveyors, and automation equipment, the LIR-T monitors current to trigger overload, undercurrent, or process-control actions and supports repair, retrofit, expansion, and replacement; common replacements include Omron, Schneider Electric, and Crouzet relays.
