Littelfuse, Inc. Monitor - Relay Output ECS61BC

The ECS61BC is a single-phase AC current monitoring relay with a built-in toroidal sensor for over or undercurrent detection, designed for 230VAC input. It features an adjustable trip point range of 2-20 A and a trip delay of 0.5-50 s, with a sensing delay on startup of 1 s. The relay has an isolated SPDT output rated at 10 A resistive at 240 VAC, with mechanical and electrical life ratings of 1 × 10⁶ and 1 × 10⁵ operations, respectively. It is encapsulated for protection against shock, vibration, and humidity, with an isolation voltage of ≥2500 V RMS and insulation resistance of ≥100 MΩ. The device mounts via two #6 (M3.5 × 0.6) screws and has dimensions of 88.9 mm × 63.5 mm × 44.5 mm. Termination is via 0.25 in. (6.35 mm) male quick-connect terminals. Operating temperature ranges from -40°C to 60°C with storage up to 85°C.
