MARS 11925 Start Capacitor
The MARS 11925 Start Capacitor is a high-performance 460-552 MFD component engineered specifically for high-torque HVAC compressor startup. This 110/125Vac start capacitor provides the critical phase shift necessary to boost starting torque by 300% to 500%, allowing single-phase motors to overcome high head pressures in systems utilizing non-bleed TXVs. Housing the electrolytic internals in a hermetically sealed, moisture-resistant black bakelite case, this round start capacitor is built to withstand rigorous field conditions while protecting against oil, grease, and dirt. As a veteran-grade motor start capacitor, the 11925 is sized for standard HVAC residential and commercial replacements, ensuring rapid acceleration to 75% of operating speed within milliseconds to prevent winding overheating. For maximum circuit protection and to avoid premature field failures, technicians should verify that the potential relay is functioning correctly, as start capacitors are designed to fail open if left in the circuit too long.
Key Benefits- Provides high-torque starting for HVACR equipment to reduce compressor lag and starting current.
- Constructed with a rugged, non-conductive bakelite case to shield against environmental contaminants.
- Equipped with dual broad-blade terminals for secure and efficient HVAC capacitor wiring in the field.
- Wide 460-552 microfarad range ensures broad compatibility with various 1/2HP to 1HP motor starting requirements.
- Compact round design facilitates easy installation in tight electrical service panels.
What happens if the capacitance rating of the 11925 is too low for my motor?
If the MFD is significantly lower than the manufacturer specifications, the motor will not generate enough starting torque to overcome the load, leading to locked rotor conditions and potential winding damage.
Can I use a 125V start capacitor on a 110V circuit?
Yes. In HVAC electrical maintenance, the voltage rating of a capacitor must meet or exceed the circuit voltage. A 125Vac rating is perfectly safe and compatible for 110Vac systems.
Why did my previous start capacitor bulge or blow the top membrane?
This typically occurs when a potential relay or start thermistor fails to drop the capacitor out of the circuit. Because electrolytic start capacitors are not designed for continuous duty, staying energized for more than a second causes rapid heat buildup and eventual failure.
