Littelfuse, Inc. Monitor - Relay Output ECS41AC

The ECS41AC is a single-phase AC current monitoring relay with a built-in toroidal sensor, designed for over or undercurrent detection in 120VAC systems. It features an adjustable trip point range of 2 to 20A and a selectable trip delay of 0.150 to 7 seconds, with a factory-set sensing delay on startup of 1 second. The relay has an isolated SPDT contact rated at 10A resistive at 240VAC, 1/4 hp at 125VAC, or 1/2 hp at 250VAC. It mounts via two #6 (M3.5 x 0.6) screws and measures 88.9 mm H x 63.5 mm W x 44.5 mm D. Input voltage tolerance is -20% to +10% for 120VAC, and it operates within a temperature range of -40°C to 60°C. Termination uses 0.25 in. (6.35 mm) male quick-connect terminals.
