Littelfuse ECSL41AD is a versatile current sensing relay with a load rating of 10 A resistive @ 240V, 1/4 hp @ 125V, and 1/2 hp @ 250V. It features 0.25 in. male quick connect terminals, adjustable trip delay (0.150 - 7s), short response time (≤75ms), and a maximum current sensor range of 300A turns for 10s. With peak detection and a toroid sensor type, it offers over or undercurrent detection and a trip point range of 2 - 20 adjustable. This relay is designed for reliable performance in varying conditions, with guaranteed sensor tolerance, ±15% trip delay vs temperature, and ±5% trip point hysteresis.
