Rectorseal M17437 40A 3-pole 240V Contactor with Lugs

Product Description

The RECTORSEAL M17437 is a 3-pole contactor rated for 40 amps at 240 volts, designed for use in HVAC and electrical load-switching applications. A contactor of this type serves as the primary switching device for compressors, condensing units, and other high-draw electrical loads, energizing and de-energizing the load circuit via a low-voltage control signal. The M17437 includes integrated lugs for secure termination connections. Based on available data, the coil operates at 24 volts AC, consistent with standard HVAC low-voltage control wiring. Licensed electricians and HVAC technicians are the typical installers for this component.

The M17437 is suited for residential and light commercial HVAC systems where a 3-pole switching configuration is required. Three-pole contactors are commonly used in three-phase condensing units and motor applications. The lug terminations make this unit appropriate for installations where solid or stranded conductors must be landed directly to the contactor body without additional terminal blocks. Note: the raw product data includes references to a 2-pole, 30-amp, 24 VAC coil configuration with 11 ohms DC resistance, 250 mA, 6 VA nominal, and 32 VA inrush — installers should verify the exact specification against the published spec sheet before installation.

Key Features

• 3-pole configuration for three-phase or multi-leg load switching
• 40-amp contact rating at 240 volts
• 24-volt AC coil for integration with standard HVAC low-voltage control circuits
• Integrated lug terminations for direct conductor landing
• Compact contactor form factor suitable for panel and equipment enclosure mounting

Compatibility

Designed as an OEM-style replacement contactor for HVAC condensing units, compressors, and motor loads requiring a 3-pole, 40-amp, 240-volt switching device with lug terminations.

Installation Notes

Installation should be performed by a licensed electrician or HVAC technician in accordance with applicable NEC requirements. Disconnect and lock out all power to the equipment before removing the existing contactor or installing the replacement. Verify coil voltage and pole configuration match the existing wiring diagram before energizing. Do not exceed the rated amperage of the contactor contacts when sizing the load circuit.
