Rectorseal M12057 Dual Run Capacitor 15/5 Mfd 370V

Product Description

The RECTORSEAL M12057 is a dual run capacitor rated at 15/5 microfarads (MFD) and 370 volts, designed for use in residential and light commercial HVAC systems. Dual run capacitors serve two motor loads simultaneously — typically the compressor and the condenser fan motor — from a single unit. The oval form factor keeps the footprint compact inside the condensing unit electrical compartment. This capacitor is installed by licensed HVAC technicians during routine maintenance, capacitor replacement, or compressor and fan motor service calls.

This capacitor is suited for split-system air conditioners and heat pumps where the original equipment calls for a 15/5 MFD, 370-volt dual run capacitor in an oval case. The 370-volt rating covers standard single-phase residential condensing unit applications. Its compact oval dimensions — 1.806 inches wide, 2.806 inches long, and 3.125 inches tall — allow it to fit in tight electrical compartments common in residential condensing units.

Key Features

• Dual run capacitor supports both compressor and condenser fan motor loads
• 15/5 MFD rating covers common residential split-system applications
• 370-volt AC rating for standard single-phase condensing units
• Oval case design fits standard condensing unit capacitor brackets
• Compact dimensions: 1.806 x 2.806 x 3.125 inches

Compatibility

Designed as an OEM-style replacement dual run capacitor for residential and light commercial split-system air conditioners and heat pumps requiring a 15/5 MFD, 370-volt oval capacitor.

Installation Notes

A licensed HVAC technician should install this capacitor. Always disconnect and lock out power to the condensing unit at the disconnect and verify zero voltage with a meter before handling the capacitor — stored charge can remain even after power is cut. Discharge the old capacitor through a resistor before removal. Follow NEC requirements for equipment wiring and reinstall terminal covers before restoring power.
