Rectorseal usa2236 Dual Run Capacitor 45/5 Mfd 370/440V

Product Description

The RECTORSEAL usa2236 is a round dual run capacitor rated at 45/5 microfarads (MFD) and compatible with both 370-volt and 440-volt systems. Dual run capacitors serve two motor windings simultaneously, supporting both the compressor and the condenser fan motor from a single component. This capacitor is a standard replacement part for HVAC service technicians working on residential and light commercial air conditioning equipment. Its round form factor is one of the most common configurations found in split-system condensing units and heat pump outdoor units.

This capacitor is suited for use in split-system air conditioners, heat pumps, and package units where a single dual run capacitor powers both the compressor start winding and the outdoor fan motor. HVAC technicians routinely replace failed or out-of-tolerance capacitors as part of seasonal maintenance, no-cool service calls, and compressor hard-start diagnostics. The 370/440-volt dual rating makes this unit compatible with the voltage range found across most residential condensing units in the field.

Key Features

• Dual run design supports compressor and condenser fan motor from one capacitor
• 45/5 MFD capacitance rating covers high-demand compressor and fan motor windings
• 370/440-volt dual-rated for broad compatibility across residential and light commercial systems
• Round form factor fits standard capacitor brackets and mounting hardware in outdoor units

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial split-system air conditioners and heat pumps requiring a round 45/5 MFD 370/440-volt capacitor.

Installation Notes

Dual run capacitors are installed by licensed HVAC technicians. Disconnect and lock out power to the condensing unit at both the disconnect and the breaker before handling any capacitor. Capacitors store a charge even after power is removed and must be safely discharged before handling. Verify MFD ratings and voltage rating on the existing capacitor before installing a replacement.
