Yueqing Huilong’s 220V relay is engineered for high - voltage switching in industrial and commercial systems, providing reliable performance in mains power applications. This electromechanical relay features a coil rated for 220V AC, with contact ratings of 30A/220V AC, suitable for switching heavy loads like motors, heaters, and lighting systems. The relay’s housing is constructed from flame - retardant polycarbonate (UL94 V - 0), while the internal contacts use silver - alloy materials to minimize arcing and wear. It incorporates a built - in suppression diode to reduce electromagnetic interference, protecting sensitive control circuits. The 220V relay supports both socket - mount and panel - mount installation, with clear terminal markings for easy wiring. Commonly used in industrial control panels, building automation, and commercial equipment, this relay offers a mechanical life of 10 million cycles and electrical life of 100,000 cycles, ensuring long - term reliability in high - voltage applications.
