Rectorseal m12210 Run Capacitor 15 Mfd 370V Round

Product Description

The RECTORSEAL m12210 is a single-capacitance run capacitor rated at 15 microfarads (MFD) and 370 volts, designed for continuous-duty operation in air conditioning and refrigeration systems. Built with an aluminum composition and a round form factor, this capacitor supports motor starting and running functions for compressors, fan motors, and blower assemblies. It carries a rated operational life of 60,000 hours and is compatible with both 50 Hz and 60 Hz electrical systems, making it a reliable replacement option for HVAC technicians working across a wide range of residential and commercial equipment.

The m12210 is suited for residential and commercial air conditioning systems and refrigeration applications. Its round housing and 4-terminal configuration allow straightforward installation in standard capacitor mounting locations. HVAC service technicians commonly use this capacitor when replacing failed or degraded run capacitors during system tune-ups, compressor replacements, or condenser fan motor repairs. The wide operating temperature range of -40 degrees F to 158 degrees F supports installations in both hot and cold climate environments.

Key Features

• 15 MFD single-capacitance rating for precise motor support

• Round aluminum housing with 4-terminal configuration for straightforward fitment
• 60,000-hour operational life rating for long-term reliability
• Compatible with 50 Hz and 60 Hz electrical systems
• Rated for operation from -40 degrees F to 158 degrees F

Compatibility

Recommended for use in residential and commercial air conditioning and refrigeration systems requiring a single-capacitance round run capacitor rated at 15 MFD and 370 volts.

Installation Notes

Run capacitors are installed by licensed HVAC technicians. Always disconnect and lock out power to the unit before servicing capacitors, as they retain a charge even after power is removed — discharge the capacitor safely using an approved resistive discharge tool before handling. Verify that the replacement MFD rating and voltage rating match or exceed the original equipment specification before installation. Follow all applicable NEC requirements and local codes when performing electrical service on HVAC equipment.
