Littelfuse, Inc. Monitor - Relay Output ECS41BD

The ECS41BD is a single-phase AC current monitoring relay with a built-in toroidal sensor, designed for overcurrent detection in 120VAC circuits. It features an adjustable trip point range of 2-20A and a trip delay of 0.5-50s, with a factory-set sensing delay on startup of 2s. The relay provides an isolated SPDT output rated at 10A resistive at 240VAC, 1/4 hp at 125VAC, or 1/2 hp at 250VAC. It is encapsulated for protection against shock, vibration, and humidity, and mounts via two #6 (M3.5 x 0.6) screws. Dimensions are 88.9 mm H × 63.5 mm W × 44.5 mm D, with 0.25 in. (6.35 mm) male quick-connect terminals. Operating temperature ranges from -40°C to 60°C, and isolation voltage is ≥2500V RMS.
