Mars 43064 Enclosed Switching Relay Dpdt 120V Plug Mount

Product Description

The Mars 43064 is an enclosed switching relay designed for use in HVAC control circuits, light commercial equipment, and electrical switching applications. This relay features a double pole double throw (DPDT) configuration, which means it controls two separate circuits simultaneously and can switch each between two positions. That makes it well suited for reversing motor direction, switching between two power sources, or controlling multiple loads from a single control signal. The relay operates on a 120 volt coil voltage, a standard in residential and light commercial HVAC systems across North America. The plug mount design allows for fast, tool-free installation into compatible relay sockets, which reduces labor time during installation or field replacement. HVAC technicians and electricians rely on switching relays like the Mars 43064 to automate control functions, interface low-voltage thermostat signals with line-voltage equipment, and protect sensitive components from direct switching loads. Mars is a well-established brand in the HVAC and refrigeration parts market, known for producing motor run capacitors, relays, contactors, and other electromechanical components built for demanding field conditions. The enclosed housing on this relay protects internal contacts from dust and debris, which extends service life in mechanical rooms, rooftop units, and equipment closets. Replacing a faulty relay with the correct DPDT configuration and coil voltage is critical to restoring proper system operation. The Mars 43064 is a direct replacement for failed or worn switching relays in a wide range of HVAC and electrical control panel applications.

• DPDT configuration controls two independent circuits from a single coil signal
• 120 volt coil voltage compatible with standard residential and light commercial HVAC control systems
• Plug mount design enables fast installation and easy field replacement without tools

Product Highlights

The Mars 43064 enclosed switching relay delivers reliable DPDT switching at 120 volts in a plug mount form factor, making it a practical replacement part for HVAC and electrical control applications.
