Mars tp-cap-30/5/440usar 30/5 Mfd 440V Dual Run Capacitor

Product Description

The MARS tp-cap-30/5/440usar is a round dual run capacitor rated at 30/5 microfarads (MFD) and 440 volts, manufactured in the USA. Dual run capacitors serve two motor windings from a single unit, supporting both the compressor and the condenser fan motor in a split-system air conditioner or heat pump. This capacitor stores and releases electrical energy to start and run those motors efficiently, maintaining stable operation under load. It is a direct replacement component installed by licensed HVAC technicians during routine maintenance or emergency service calls.

This capacitor is designed for residential and light commercial HVAC applications, primarily split-system air conditioners and heat pumps that use a single dual run capacitor to support both the compressor and fan motor circuits. The round form factor and 440-volt rating make it a widely applicable replacement part for systems using 30/5 MFD dual run capacitors. The USA-made construction meets standard expectations for quality in the replacement capacitor market.

Key Features

• Dual run design supports compressor and condenser fan motor from a single capacitor
• Rated at 30/5 MFD to match common residential and light commercial HVAC requirements
• 440-volt rating provides compatibility with standard single-phase HVAC motor circuits
• Round form factor fits standard capacitor brackets and mounting hardware
• Manufactured in the USA

Compatibility

Designed as an OEM-style replacement for residential and light commercial split-system air conditioners and heat pumps requiring a round 30/5 MFD 440-volt dual run capacitor.

Installation Notes

Dual run capacitors must be installed by a qualified HVAC technician. Always disconnect and lock out power to the unit before handling capacitors, as they can retain a lethal charge even after power is removed — discharge the capacitor safely before touching terminals. Verify the MFD ratings and voltage rating of the replacement match the original unit nameplate exactly before installation. Follow NEC guidelines and local codes for low-voltage motor circuit service.
