Littelfuse, Inc. Monitor - Relay Output ECS6HAH

The ECS6HAH is a single-phase AC current sensor in the ECS Series, designed for overcurrent monitoring with a fixed trip delay of 6 seconds. It operates from 230VAC and detects current in the 5 to 50A range using a built-in toroidal sensor. The device features an isolated SPDT relay output rated for 10A resistive at 240VAC, with a trip point tolerance of ±2.5% for ranges above 26A. Trip delay accuracy is guaranteed within ±10%, and sensing delay on startup is fixed at 6 seconds. The unit is encapsulated, surface-mounted with two #6 screws, and measures 88.9 mm H × 63.5 mm W × 44.5 mm D. It operates from -40°C to 60°C and has an input voltage tolerance of -20% to +10% for 230VAC. Relay contacts provide electrical isolation with a dielectric strength of ≥2500V RMS.
