Littelfuse ESDR420A0 is an encapsulated solid-state relay designed for reliable control of electrical loads. It has a load rating of 1A steady state and 10A inrush at 45°C, with 0.25 in. male quick connect terminals for easy installation. It operates at input AC frequencies of 50/60Hz with a tolerance of ±20%. The relay offers repeat accuracy of ±0.1% or 20ms, insulation resistance greater than 100, and a setpoint vs ambient temperature and operating voltage variation of ≤±2%. With a power consumption of ≤2VA, time delay tolerance of ≤±5%, and reset time of ≤150ms, it provides efficient and reliable operation. Its dielectric breakdown exceeds 2000V terminals to mounting surface, and it has an output voltage drop of 2.5V @ 1A. The relay has a long electrical life of 1 x 10⁶ cycles and mechanical life of 1 x 10⁷ cycles. Additionally, it has a low open state leakage current of 2.5A @230V ac.
