MARS 11090 Start Capacitor
The MARS 11090 Start Capacitor is a heavy-duty motor start capacitor engineered for high-torque applications in residential and commercial HVACR systems. With a capacitance rating of 430-516 MFD and a dual voltage capacity of 220/250VAC, this component provides the essential phase-shifted current surge required to initiate compressor and fan motor rotation. Constructed within a hermetically sealed black Bakelite case, the unit is specifically designed to resist moisture, oil, and grease, ensuring long-term reliability in harsh mechanical environments. This non-polarized aluminum electrolytic capacitor features 1/4-inch quick disconnect terminals for efficient field replacement. Operating within a frequency range of 50/60 Hz and a temperature threshold of -40°C to 65°C, the MARS 11090 is a versatile solution for increasing starting torque and reducing initial load on fractional horsepower motors. As a UL 810 recognized component, it meets secondary standard requirements for safety and performance in the field, making it a staple for any technician's service van.
Key Benefits
- Universal Field Replacement: Compact physical dimensions allow for easy installation in standard motor control compartments, serving as a direct replacement for many OEM start capacitors.
- Rugged Environmental Protection: The phenolic resin housing prevents dielectric breakdown caused by environmental contaminants like dirt or humidity.
- High Starting Torque: Optimized for 220V and 250V circuits to ensure rapid motor acceleration, which protects internal motor windings from excessive heat during the start cycle.
- PCB-Free Construction: Manufactured without polychlorinated biphenyls to comply with modern environmental safety regulations.
Common Questions
- Can I use this 430-516 MFD capacitor if my old one is 250VAC? Yes, the 11090 is rated for 220/250VAC applications, making it suitable and safe for any system operating at or below 250 volts.
- What happens if the capacitance rating doesn't match perfectly? This capacitor covers a range (430-516 MFD). Always ensure your motor's required MFD falls within this range to maintain proper starting torque without damaging the motor.
- Is this suitable for intermittent duty? Yes, as a start capacitor, it is designed for intermittent use to kick-start the motor and should be removed from the circuit by a relay or centrifugal switch once the motor reaches speed.
