MARS 11037 Capacitor
The MARS 11037 Capacitor is a professional-grade motor start capacitor engineered to provide the high-torque boost necessary for heavy-duty HVACR compressors and electric motors. Rated for a capacitance range of 400-480 MFD at 165V, this component is a reliable solution for high-demand startup cycles in commercial and residential equipment. Built with a rugged, hermetically sealed bakelite case, the MARS 11037 protects internal elements from oil, moisture, and debris, ensuring stable HVAC startup performance in harsh environments.
For contractors performing capacitor replacement, the MARS 11037's compact design (approx. 3-3/8" height and 1-7/8" diameter) allows it to fit standard mounting brackets in a wide variety of air conditioning and refrigeration units. It is designed to momentarily increase starting torque and is typically disconnected by a centrifugal switch or relay once the motor reaches operational speed. This 400-480 MFD 165V capacitor is an industry-standard part for restoring efficiency and preventing motor "humming" or hard-start failures.
Key Benefits:
- High Starting Torque: Provides the critical electrical surge required for compressor startup in high-static applications.
- Durable Construction: Heavy-duty bakelite housing is resistant to impact and environmental contaminants.
- Versatile Compatibility: Standard 165V rating and capacitance range make it an ideal service-truck staple for HVAC motor repair.
- Industry Standard Sizing: Compact footprint facilitates easy installation in tight control boxes.
- Reliable Performance: Engineered and tested to meet stringent performance requirements for electrical motor components.
Common Questions:
Can I use this 165V capacitor if my original was 110V/125V?
Yes, in capacitor physics, you can typically use a capacitor with a higher voltage rating as long as the MFD (microfarad) range matches your original specifications. Using a 165V rated capacitor in a 110V application provides additional overhead for voltage spikes.
What is the difference between a start capacitor and a run capacitor?
A start capacitor like the MARS 11037 is designed for short-term use during the initial seconds of motor startup to overcome inertia. It must be paired with a relay or switch to disconnect it once the motor is running, unlike run capacitors which stay in the circuit continuously.
Why is my motor humming but not starting?
A humming motor or compressor often indicates a failed start capacitor. If the 400-480 MFD 165V unit is leaking fluid or appears bulged, it should be replaced immediately to prevent motor winding damage.
