For professional contractors servicing domestic or commercial refrigeration and air conditioning systems, the MARS 11950 Start Capacitor is a reliable, high-performance component designed for heavy-duty motor starting applications. Rated for 161-193 Microfarad (MFD) and 220/250Vac, this round electrolytic capacitor provides the essential high-torque surge required to initiate compressor and fan motor operation under demanding load conditions. Constructed with a hermetically sealed black bakelite case, the MARS 11950 is engineered to withstand moisture, oil, and grease, ensuring long-term stability in harsh mechanical environments. This unit features standard 1/4 inch dual-blade quick-connect terminals for rapid installation during a critical AC repair or system overhaul. Operating within a temperature range of -40°C to 65°C, this motor start capacitor ensures consistent performance across diverse climates, making it a critical stock item for any technician’s truck to address an air conditioner not cooling or a stalled motor. Key Benefits: High Torque Starting: Optimized for providing the intensive boost necessary for compressors and motors to overcome initial resistance. Environmental Protection: The phenolic case construction ensures resistance to grease and moisture common in HVACR environments. Universal Compatibility: Standard 1/4" dual quick-connect terminals allow for easy replacement of most 161-193 MFD capacitors in this voltage class. Compact Round Form Factor: Measures approximately 3-3/8" in height and 1-3/4" in diameter, fitting standard mounting brackets in compact electrical housings. Common Questions: Can I use this 250V capacitor to replace a 220V start capacitor? Yes, the 220/250Vac rating is compatible with lower voltage applications; always ensure the MFD range matches your motor's specific requirements. What are the signs that my motor start capacitor is failing? Common indicators include a humming motor that fails to turn, tripped breakers upon startup, or visible bulging and leaking from the capacitor casing. Is this compatible with 50Hz and 60Hz systems? Yes, this MARS capacitor is engineered for use in standard AC electrical systems across typical industrial frequencies.
