MARS 11910 Start Capacitor
The MARS 11910 Start Capacitor is a high-performance electrical component engineered for intermittent duty in single-phase AC induction motors. This 108-130 Microfarad unit is specifically designed to provide the high starting torque required to bring compressors and fan motors up to speed quickly in HVACR systems. Rated for 110/125Vac at 50/60 Hz, this Round Start Capacitor features a rugged, non-polarized phenolic resin case that offers superior moisture and oil resistance for demanding mechanical room environments. With a compact physical footprint of 1-3/8" by 2-3/4" and standard 1/4-inch male quick-connect terminals, it serves as a reliable direct replacement for stock capacitors in water pumps, pool pumps, and light commercial refrigeration units. This MARS capacitor meets Electronic Industries Association (EIA) Standard RS-463 type 2, ensuring stable capacitance and operational integrity across an operating temperature range of -40°F to 149°F.
Key Benefits
- Delivers high starting torque to fractional horsepower motors and compressors, ensuring rapid acceleration and reduced winding heat.
- Features a durable phenolic case that protects internal electrolytic components from environmental contaminants and physical vibration.
- Compatible with HVAC motor start circuits, well pumps, and air compressors requiring 125V start assistance.
- Constructed from PCB-free materials, meeting modern safety and environmental compliance standards for professional contractors.
- Standardized dual-blade terminals simplify installation and ensure secure electrical connections during field service.
Common Questions
Can I use this capacitor if my original is rated for 110V?
Yes. This unit is rated for 110/125Vac. You can always use a capacitor with a voltage rating equal to or higher than the original, provided the microfarad (uF) range matches your motor specifications.
How do I know if I need a bleed resistor with this start capacitor?
Technicians typically apply a bleed resistor when using a start capacitor with certain starting relays. This prevents arcing across the relay contacts by discharging the capacitor when the motor is not running.
Is the 108-130 MFD range compatible with a 120 uF rating?
Yes. Since this capacitor covers the range from 108 to 130 uF, it is the correct replacement for any motor specified for 120 uF within this voltage class.
