Littelfuse, Inc. Monitor - Relay Output ECS41BH

The ECS41BH is a single-phase AC current sensor with a built-in toroidal current transformer for overcurrent monitoring, designed for use with 120VAC input. It features an adjustable trip point range of 2-20A and a trip delay of 0.5-50s, with a sensing delay on startup of 6s. The device includes an isolated SPDT relay output rated for 10A resistive at 240VAC, 1/4 hp at 125VAC, and 1/2 hp at 250VAC. It is mounted via two #6 (M3.5 x 0.6) screws with dimensions of 88.9 mm H × 63.5 mm W × 44.5 mm D and uses 0.25 in. (6.35 mm) male quick-connect terminals. The circuitry is encapsulated for protection against shock, vibration, and humidity. Operating temperature ranges from -40°C to 60°C, with storage up to 85°C and humidity tolerance up to 95% non-condensing.
