Littelfuse ECSH41BC is a versatile current sensing relay suitable for various applications. With a load rating of 10A resistive @ 240V, it offers reliable performance. It features 0.25in male quick connect terminals and has adjustable trip delay range from 0.5-50s. The sensor type is a toroid with a maximum current sensor range of 50A turns. With a trip point range of 2-20 adjustable and a response time of ≤75ms, it ensures accurate and rapid detection. It operates at an input AC line frequency of 50/60Hz and has a wide input tolerance of -20% to +10%. The sensor mode can be switched between over and undercurrent, providing flexibility. The ECSH41BC also has trip point hysteresis of ±5% and trip delay sensing on startup. It is suitable for use in high humidity conditions (95% non-condensing) and offers reliable insulation with an insulation resistance ≥100.
