Littelfuse, Inc. Monitor - Relay Output ECSW6MBHT

The ECSW6MBHT is a single-phase AC window current sensor for monitoring overcurrent and undercurrent conditions in 230VAC systems, with a trip point range of 2 to 20A and a trip delay adjustable from 0.5 to 50 seconds. It features a built-in toroidal sensor, isolated SPDT relay output rated at 10A resistive at 240VAC, and terminal block connections. The unit includes switch-selectable latching or auto-reset operation, zero current detection, and a sensing delay of 6 seconds on startup. It operates over a temperature range of -40°C to 60°C and is mounted with two #6 (M3.5 x 0.6) screws. Dimensions are 88.9 mm high, 63.5 mm wide, and 44.5 mm deep. Surge protection complies with IEEE C62.41-1991 Level A, and isolation voltage is ≥2500V RMS.
