This professional-grade component provides the critical phase shift required for high-torque \u003cstrong\u003econdenser fan motors\u003c\/strong\u003e, blower assemblies, and refrigeration compressors. Built with a rugged drawn steel case and utilizing non-PCB, biodegradable synthetic oil, it maintains dielectric stability across an operational temperature range of -40°F to 185°F. The quad-blade quick-connect terminals facilitate efficient field wiring, while the ±5% capacitance tolerance ensures motor performance stays within OEM specifications. As a direct \u003cstrong\u003eCR10X440 cross reference\u003c\/strong\u003e for CAP100000440LAS, this unit is an ideal \u003cstrong\u003e10 uF 440V capacitor\u003c\/strong\u003e replacement for technicians servicing residential and light commercial equipment. Its 440VAC rating offers increased dielectric strength, making it a reliable upgrade for systems originally utilizing 370V components.\u003c\/p\u003e\n\n\u003cstrong\u003eKey Benefits for Technicians:\u003c\/strong\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUniversal Application:\u003c\/strong\u003e Designed as a \u003cstrong\u003e10 MFD HVAC run capacitor\u003c\/strong\u003e suitable for furnaces, AC units, and heat pumps.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnhanced Durability:\u003c\/strong\u003e The 440V rating provides a superior safety margin against voltage surges compared to standard 370V alternatives.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompact Oval Profile:\u003c\/strong\u003e Fits standard mounting brackets in tight electrical control boxes and furnace vestibules.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSafety Rated:\u003c\/strong\u003e Features internal pressure-sensitive interrupter protected by a durable steel housing for reliable circuit interruption.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eCommon Service Questions:\u003c\/strong\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use this 440V capacitor to replace a 10 MFD 370V capacitor?\u003c\/strong\u003e\u003cbr\u003e\nYes. In HVACR service, you can always increase the voltage rating of a run capacitor, provided the microfarad (MFD\/µF) rating remains identical. Using a 440V rated part in a 370V application often extends the component life due to the higher dielectric threshold.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow do I test if the CR10X440 is failing?\u003c\/strong\u003e\u003cbr\u003e\nUse a multimeter with a capacitance setting to verify the 10 µF output. If the reading falls outside the ±5% tolerance, or if the steel casing shows signs of bulging or leaking oil, the capacitor must be replaced to prevent motor overheating and winding failure.\u003c\/p\u003e\n\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
