About HVACR Relays

Many single-phase motors, compressors and other components used in HVACR need an external relay or switch to help it start. The main purpose of the HVACR relay is to bring in an additional electrical circuit, giving the motor the extra boost it needs to start. Other components used in HVACR include cooling equipment relays and fan control switches - you’ll find both in our large inventory of products.
