Description
Littelfuse TS1421 is a compact and reliable thermal time delay relay. It features a 1 A steady state output load rating, with a 10 A inrush rating at 60°C. The termination type is 0.25 in. (6.35 mm) male quick connect terminals for easy installation. It operates at an input AC line frequency of 50/60 Hz with a tolerance of ±20%. With an encapsulated circuitry and a humidity resistance of 95% relative non-condensing, this relay ensures durability and reliable performance. With a repeat accuracy of ±2% or 20 ms, whichever is greater, it provides precise and consistent timing. The insulation resistance of ≥100 ensures safety and reliability. It has a setpoint vs ambient temperature and operating voltage variation of ≤±10%. The time delay type is analog, and the time delay tolerance is ≤±10%. With a high dielectric breakdown of ≥2000V, it offers excellent insulation. The output voltage drop is ≅2.5 V at 1 A. The recycle time is ≤16 ms after timing and 0.1% of max. time delay or 75 ms during timing. The minimum output holding current is 5 mA. Overall, the Littelfuse TS1421 is a dependable and versatile thermal time delay relay suitable for various applications.
