Rectorseal m17435 Contactor 40A 3-pole 24V with Lugs

Product Description

The RECTORSEAL m17435 is a 3-pole contactor rated at 40 amps with a 24-volt control coil and integrated lug terminations. Contactors are electromechanical switching devices that open and close high-voltage load circuits in response to a low-voltage control signal. This unit is designed for use in HVAC systems where reliable switching of compressor and condenser fan motor loads is required. The lug-style terminals provide a secure, code-compliant connection point for line and load conductors. Licensed HVAC technicians are the primary installers of this device in both new equipment and replacement service scenarios.

This contactor is suited for residential and light commercial HVAC applications, including split-system air conditioners and heat pumps. It operates on a standard 24-volt control circuit, which is the most common low-voltage control voltage found in residential and commercial thermostat wiring. The 3-pole configuration allows it to switch three line conductors simultaneously, making it appropriate for three-phase or multi-leg load applications where complete circuit interruption is required.

Key Features

• 40-amp load rating for compressor and condenser fan motor circuits
• 3-pole design switches all three line conductors simultaneously
• 24-volt control coil compatible with standard thermostat control circuits
• Lug-style line and load terminals for secure conductor termination
• Compact footprint: 3.3 inches wide, 2.6 inches tall, 4.1 inches deep

Compatibility

Designed as an OEM-style replacement contactor for residential and light commercial HVAC systems requiring a 3-pole, 40-amp, 24-volt contactor with lug terminations.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with NEC requirements and local codes. Disconnect and lock out all power to the unit before removing the existing contactor or handling load terminals. Verify the incoming voltage and ampacity match the contactor rating before energizing. Do not exceed the rated load current, and ensure all lug connections are properly torqued per the terminal manufacturer guidance stamped on the device.
