RGC1A23A42KGE is a 1-phase solid state contactor with integrated heatsink designed for industrial switching applications. It features a rated operational voltage of 230V AC (+10% -15%), a blocking voltage of 800Vp, and a rated operational current of 43 AAC at 40°C with an I²t rating of 18000 A²s. The device supports control voltages of 20-275 VAC or 24-190 VDC, includes integrated voltage transient protection with a 275V varistor, and offers zero-cross switching for reduced electromagnetic interference. With screw/box clamp power and control connections, a product width of 35mm, and compliance with EN/IEC60947-4-2, EN/IEC60947-4-3, and UL508 standards, this relay is ideal for motor control, heating element switching, and general industrial load management where space efficiency and reliability are critical.
