Resideo by Honeywell R845A1030 120V DPST Switching Relay

The Resideo by Honeywell R845A1030 is a heavy-duty 120-volt switching relay designed for HVAC control applications. This double pole, single throw (DPST) relay provides reliable switching for heating, cooling, and ventilation systems.

Key Features:

• 120VAC operating voltage for standard residential and commercial applications
• DPST (Double Pole, Single Throw) configuration provides two separate circuits controlled by one coil
• Line voltage switching capability for direct control of HVAC equipment
• Compact design for easy installation in control panels and junction boxes
• Durable construction for long-term reliability in demanding environments
• Compatible with thermostats, time clocks, and other low-voltage control devices

This switching relay is commonly used to control furnace fans, air conditioning compressors, and other line-voltage HVAC components. The DPST configuration allows simultaneous switching of two separate circuits, making it ideal for applications requiring synchronized control of multiple loads.
