The Allstar 005017 Capacitor is a motor start capacitor rated at 43–53 MFD and 250 VAC, designed to deliver the extra starting torque required by single-phase induction motors. It is commonly selected as a replacement part when equipment specifies a 43–53 microfarad, 250-volt AC start capacitor, supporting a wide range of residential and commercial applications such as garage door openers, gate operators, pumps, compressors, and blower motors. Matching the motor or control’s nameplate ratings ensures proper compatibility and dependable startup performance.
Built for intermittent duty during startup, this start capacitor should not be used in place of a continuous run capacitor. It is suitable for typical 50/60 Hz AC systems and should be installed according to the equipment manufacturer’s wiring diagram and local electrical codes. For safety, disconnect power before servicing, discharge the capacitor prior to handling, and replace only with a unit that matches the specified microfarad range and an equal or higher voltage rating. Proper mounting and secure connections help maintain reliable operation and extend component life.
