RGC1B60D15KGU is a single-phase solid state contactor with integrated heatsink designed for industrial switching applications requiring instant-on (IO) switching mode. It features a rated operational voltage of 600V with 1200Vp blocking voltage, a rated operational current of 20AAC at 40°C with an I²t value of 525A²s, and a compact 17.5mm width with low depth profile. The device supports control voltages of 4-32VDC or 20-275VAC (24-190VDC), includes integrated voltage transient protection with a 625V varistor, and offers screw or box clamp connection options for both control and power terminals. This relay is ideal for motor control, heating element switching, and other industrial automation applications where reliable solid-state switching with minimal panel space is required, conforming to EN/IEC 60947-4-2, EN/IEC 60947-4-3, and UL508 standards.
