Littelfuse ESDR420A4 is a compact and rugged solid-state relay designed for industrial applications. It features a steady state output load rating of 1 A and can handle inrush currents up to 10 A at 45°C. The termination type is 0.25 in. male quick connect terminals for easy installation. With an input AC line frequency of 50/60 Hz and a tolerance of ±20%, this relay offers reliable performance. It is encapsulated and has a power consumption of ≤2 VA. With a reset time of ≤150 ms and a repeat accuracy of ±0.1% or 20 ms, whichever is greater, this relay ensures accurate and efficient operation. It has a dielectric breakdown of ≥2000V between terminals and mounting surface, ensuring safety. The output voltage drop is 2.5V at 1 A, minimizing power loss. With a life cycle of 1 x 10⁶ electrical and 1 x 10⁷ mechanical cycles, this relay is durable and long-lasting. It has a humidity resistance of 95% non-condensing and an insulation resistance of ≥100M Ω. The open state leakage current is 2.5 A at 230 V AC.
