Description
Dayton 4X429A Oil Capacitor 7.5 MFD 370 VAC 50/60 Hz Motor Run New
The Dayton 4X429A is an oil-filled motor run capacitor rated at 7.5 MFD and 370 VAC, 50/60 Hz. It is housed in an oval aluminum can with dual quick-connect terminal wells and is new old stock — unused and never installed. Manufactured by Dayton Electric Mfg. Co., this capacitor carries a 5000 AFC short-circuit protection rating and is clearly labeled "No PCBs," indicating a non-PCB dielectric fluid.

Applications
Motor run capacitors like the Dayton 4X429A are used to improve the efficiency and running torque of single-phase AC induction motors. They remain permanently in the motor circuit during operation — unlike start capacitors, which drop out after startup — maintaining a phase shift between the main and auxiliary windings that keeps the motor running smoothly and efficiently. Common applications include HVAC compressors, condenser fan motors, furnace blower motors, air handlers, pumps, and other single-phase motor-driven equipment. The 370 VAC rating is a standard value widely used in residential and light commercial HVAC systems. Oval-can oil-filled capacitors are the traditional industry-standard form factor for these applications and remain in everyday use for original-equipment replacements and service repairs.
This Dayton 4X429A Oil Capacitor is new old stock. The unit has not been installed or used. The aluminum can shows some light surface oxidation and minor cosmetic marks consistent with storage — typical for older new-stock components — but the capacitor itself is unused. Both terminal wells and quick-connect contacts are intact and free of damage. Please view our photo set and contact us if you have any questions.
