MARS 12995 Run Capacitor

The MARS 12995 Run Capacitor is a high-spec 5 MFD 370V round capacitor engineered for continuous duty in residential and commercial HVACR systems. Designed to stabilize current and optimize motor torque, this component is a standard replacement for condenser fan motors and furnace blower motors requiring a precise 5 microfarad capacitance. Built with a heavy-duty aluminum case and non-PCB oil, it features a physical interrupter safety mechanism that prevents case rupture in the event of an internal failure. As a veteran-grade HVAC motor run capacitor, the 12995 is rated for 60,000 hours of operational life and maintains a strict +/- 5% tolerance. The 370 VAC rating ensures reliable performance across standard single-phase applications, while the 1/4-inch quad terminals allow for quick, secure wiring during field service.

Key Benefits for Technicians:

• Broad Compatibility: Directly replaces multiple OEM 5 MFD 370 volt capacitors, making it a "truck stock" essential for air conditioning and refrigeration service.
• Safety Certified: UL and CUL listed with an integrated UL-recognized internal pressure interrupter for maximum protection.
• High Durability: Rated for a temperature range of -40°C to +70°C, ensuring stability in extreme attic or outdoor condenser environments.
• Professional Grade: Features standardized quad blade terminals for efficient multi-wire connections.

Common Questions:

Can I use a 440V capacitor to replace this 370V model?
Yes. A 440V capacitor is a suitable upgrade as it can handle higher voltage stress, provided the 5 MFD capacitance and physical dimensions remains identical. You should never "down-rate" a capacitor by using a voltage lower than 370V.

What are the symptoms of a failing MARS 12995?
Common indicators include a humming fan motor that fails to start, a "bulged" or distorted top on the aluminum casing, or a capacitance reading outside of the +/- 5% tolerance when tested with a multimeter.

Does this capacitor support 50/60 Hz systems?
Yes, the MARS 12995 is rated for dual-frequency operation (50/60 Hz), making it suitable for a wide range of domestic and international motor applications.
