Rectorseal M12283 Dual Run Capacitor 35/5 Mfd 440V

Product Description

The RECTORSEAL M12283 is a dual run capacitor rated at 35/5 microfarads (MFD) and 440 volts, designed to support both the compressor and fan motor in a single round housing. Dual run capacitors provide the starting and running torque required to keep split-system and package unit motors operating efficiently. This round capacitor is a standard form factor used throughout the HVAC industry and is installed by licensed HVAC technicians during routine service calls, compressor replacements, and fan motor changeouts. At 2.0 inches wide and 4.375 inches tall, it fits most standard capacitor brackets without modification.

This capacitor is suited for residential and light commercial air conditioning systems where a single component handles both the compressor and condenser fan motor circuits. It is commonly installed in rooftop package units, split-system condensing units, and heat pumps. The 440-volt rating makes it compatible with both 208-volt and 240-volt single-phase applications, giving technicians a single stocking unit for a broad range of service situations.

Key Features

• Dual run capacitor supports compressor and fan motor from one component
• 35/5 MFD rating covers standard compressor and condenser fan motor requirements
• 440-volt rating compatible with 208-volt and 240-volt single-phase systems
• Round housing fits standard capacitor mounting brackets
• Compact footprint: 2.0 inches wide by 4.375 inches tall

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial split-system air conditioners, heat pumps, and package units requiring a 35/5 MFD, 440-volt round capacitor.

Installation Notes

Capacitor replacement is performed by licensed HVAC technicians. Always disconnect and lock out power to the unit before handling capacitors, as they retain a lethal charge even after power is removed — discharge the capacitor through a resistor before touching terminals. Follow all applicable NEC requirements and local codes for electrical component replacement. Do not substitute a capacitor with a lower voltage rating or a MFD value outside the equipment manufacturer's specified tolerance range.
