Littelfuse THD2C433 is a compact, encapsulated time delay relay. It has a maximum load rating of 20 A steady state and 200 A inrush. It features 0.25 in. male quick connect terminals for easy installation. With input AC line frequencies of 50/60 Hz and an input tolerance of ±20%, it provides reliable performance. The relay has a repeat accuracy of ±0.5% or 20 ms and insulation resistance of ≥100. It operates within a humidity level of 95% non-condensing. The setpoint vs ambient temperature and operating voltage is ≤±2%, ensuring precise functionality. The time delay tolerance is ≤±1%, with a reset time of ≤150 ms. The relay offers strong dielectric breakdown at ≥2000V between terminals and mounting surface. It has a low output voltage drop of ≅2.5 V at rated current and a minimal open state leakage current of ≅5 A at 230 V AC. The relay requires a minimum output load current of 100 A.
