MARS 11917 Start Capacitor
The MARS 11917 Start Capacitor is a high-torque electrolytic motor start capacitor engineered for demanding single-phase HVACR applications. This 216-259 MFD start capacitor provides the essential phase-shift and high starting current required to initialize heavy-duty compressor motors and electric fans under load, particularly in systems utilizing a non-bleed TXV. Encased in a rugged, moisture-resistant black bakelite case, the 11917 maintains operational stability at 110/125Vac across a 50/60Hz frequency range. As a direct replacement for standard round start capacitors in this microfarad range, it ensures efficient terminal-to-start winding power delivery, effectively reducing in-rush current duration. Its compact dimensions (approximately 1-3/8 inch diameter) allow for seamless housing within existing electrical compartments, ensuring a reliable HVAC motor replacement solution for technicians seeking to restore torque and prevent compressor overheating.
Key Benefits for Technicians- Optimal Capacitance Range: Provides 216-259 microfarads to ensure reliable starting torque for 1/8 to 1/2 HP motors.
- Robust Environmental Protection: The hermetically sealed bakelite housing protects internal components from oil, dirt, and moisture common in mechanical rooms.
- Universal Compatibility: Operates efficiently at 110V and 125V, serving as a versatile Mars 11917 replacement for various residential and commercial units.
- Electrical Efficiency: Designed to drop out of the circuit within milliseconds via a potential relay, protecting the start windings from thermal stress.
Can I use the MARS 11917 to replace a 233-280 MFD capacitor?
Technicians should stick to within 10% of the original MFD rating. This 216-259 MFD capacitor is specifically sized for applications requiring this exact range to prevent winding damage or starting failure.
What causes a start capacitor like the 11917 to fail?
Common failure points include voltage surges, excessive heat, or a faulty potential relay that keeps the capacitor in the circuit too long, leading to capacitor bulging or leaking fluid.
Does this capacitor require a bleed resistor?
While many HVAC start capacitors include a pre-installed resistor, always verify your system requirements. A bleed resistor is recommended to discharge residual voltage and protect the relay contacts.
