Resideo R4222B1082 General Purpose Relay W/SPDT Switching 12 Amp 120V

The Resideo R4222B1082 General Purpose Relay is an electrical switch designed for HVAC systems to provide effective control in homes and commercial settings. It is of SPDT switch type and turns on circuits with a 120V coil and has a 1/4” double quick connect. It switches between the contacts depending on the current that flows through it, and it responds to system signals at the 50/60 Hz frequency within the temperature range of -20°F to 155°F. Typically installed in air handlers, boilers as well as fan centers, it handles a 12A current for optimum performance. That increases durability of HVAC systems, used wiring and provides controllability and maintainability towards long-term operation in severe circumstances.
