Yueqing Huilong’s 120V relay is designed for medium - voltage industrial applications, providing reliable switching for commercial and industrial systems. This electromechanical relay features a coil rated for 120V AC, with a contact rating of 20A/120V AC, suitable for switching resistive and inductive loads. The relay’s housing is made from flame - retardant polyamide (UL94 V - 0), while the internal components include silver - alloy contacts that reduce arcing and ensure long - term conductivity. It incorporates a built - in flyback diode to suppress voltage spikes, protecting connected circuitry. The 120V relay supports both socket - mount and screw - mount installation, with clear terminal markings for easy wiring. Commonly used in HVAC systems, lighting panels, and commercial kitchen equipment, this relay offers a mechanical life of 10 million cycles and electrical life of 100,000 cycles, ensuring reliable operation in continuous - use environments.
