MARS 11949 Start Capacitor
The MARS 11949 Start Capacitor is a high-duty cycle component engineered for precise torque assistance in single-phase electric motor applications. Operating within a capacitance range of 145-175 Microfarads (MFD) and rated for 220/250VAC, this round electrolytic capacitor provides the phase-shift necessary for high-inertia startups in HVACR compressors and pump motors. Its round compact design measures approximately 1-3/4 inches in diameter by 3-3/8 inches in height, facilitating a direct fit in standard motor canopy enclosures. Built to withstand demanding thermal conditions, the MARS 11949 features a rugged phenolic case and reliable dual quick-connect terminals for secure wiring. When replacing an OEM start capacitor, verify that the 220/250V rating is equal to or greater than the original part to prevent dielectric breakdown. Utilizing a 145-175 MFD start capacitor significantly reduces current draw during the locked-rotor amperage (LRA) phase, protecting motor windings from premature heat stress and ensuring consistent cycle engagement.
Key Benefits:- Optimized Starting Torque: Delivers the high-capacitance boost required for heavy-duty HVACR compressors and motor loads.
- Professional Grade Reliability: Engineered with a moisture-resistant phenolic case to ensure consistent performance in high-humidity environments.
- Standardized Fit: The round start capacitor geometry allows for seamless integration into existing mounting brackets.
- Dual Terminals: Equipped with quick-connect terminals for efficient field installation and secure electrical contact.
- Can I use a higher voltage capacitor as a replacement? Yes, you can replace a lower voltage capacitor with the 220/250Vac 11949, provided the capacitance range (MFD) matches the original specifications.
- How do I know if my start capacitor has failed? Signs of a faulty MARS 11949 include physical bulging, fluid leakage, or the motor humming without turning.
- Is a bleed resistor necessary? For applications involving potential relays, technicians typically install a bleed resistor across the terminals to discharge the capacitor safely after the starting circuit opens.
