Littelfuse TSS624 is a compact and reliable thermal overload sensor. It features a 1A steady-state output load rating with a 10A inrush at 60°C. It has 0.25 inch male quick connect terminals for easy installation. The frequency tolerance for the input AC line is ±20%, and it can operate at 50/60Hz. The device is encapsulated and has a power consumption of ≤2VA. It has a reset time of ≤150ms and a time delay tolerance of ≤±5%. The insulation resistance is ≥100, and the dielectric breakdown is ≥2000V. The output voltage drop is approximately 2.5V at 1A, and the open state leakage current is approximately 5A at 230V AC. It has a humidity rating of 95% non-condensing and repeat accuracy of ±2% or 20ms, whichever is greater. The setpoint vs ambient temperature and operating voltage is within ≤±10%. The initiate time is ≤20ms. This thermal overload sensor is a reliable solution for various applications.
