Littelfuse ASTUA3 is an encapsulated time delay relay with a steady state output load rating of 0.7 A and 10 A inrush. It has push-on terminal blocks for wire connection, accepts #14 AWG wire, and operates at a frequency of 50/60 Hz. With a repeat accuracy of ±1% or 50 ms, it provides a reliable and precision-controlled operation. The microcontroller-based time delay type ensures accurate and consistent performance. It offers surge protection, a reset time of ≤300 ms, and a dielectric breakdown of ≥2000V. The ASTUA3 is designed for efficiency and flexibility, featuring a knob with a dial and two switches to select one of four multipliers.
