Rectorseal m91431 Definite Purpose Contactor 40A 3P 24V

Product Description

The RECTORSEAL m91431 is a compact, definite purpose contactor rated for 40 amps at 24 volts AC with a 3-pole configuration. Definite purpose contactors are designed for high-cycle switching applications in HVAC and refrigeration systems, where reliable load control is essential. This unit features box lug terminations for secure conductor connections. The compact body fits into tight electrical enclosures common in packaged units and split systems. Licensed HVAC technicians and refrigeration mechanics are the typical installers for this class of component.

This contactor is suited for commercial and residential HVAC equipment including condensing units, packaged rooftop units, and refrigeration compressor circuits. The 24-volt coil voltage is standard for low-voltage control wiring common in these systems. The 3-pole design supports three-phase load switching, making it applicable to light commercial three-phase compressor and fan motor circuits where a compact footprint is required.

Key Features

• 40-amp load rating supports compressor and fan motor applications
• 3-pole configuration for three-phase circuit switching
• 24 VAC coil voltage compatible with standard low-voltage HVAC control systems
• Box lug terminations for reliable, tool-secured conductor connections
• Compact body designed to fit space-constrained electrical enclosures
• Definite purpose rated for high-cycle HVAC and refrigeration duty

Compatibility

Designed as an OEM-style replacement definite purpose contactor for residential and light commercial HVAC condensing units and refrigeration equipment requiring a 40-amp, 3-pole, 24 VAC coil contactor with box lug terminations.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified electrician in accordance with NEC requirements and applicable local codes. Disconnect and lock out all power to the unit before removing the existing contactor or making any wiring connections. Ensure conductor sizing matches the 40-amp rating and that all box lug connections are tightened securely to prevent arcing. Verify coil voltage at the control circuit matches 24 VAC before energizing the replacement contactor.
