Franklin Electric 155000000 Motor Run Capacitor 45MFD 370V

Product Description

The FRANKLIN ELECTRIC 155000000 is an AC motor run capacitor rated at 45 microfarads (MFD) and 370 volts AC. Motor run capacitors stay in the circuit during normal operation, providing the phase shift needed to keep single-phase induction motors running efficiently and smoothly. This capacitor is designed for continuous-duty use and maintains the correct running torque for 3 HP single-phase motors. Licensed HVAC technicians and pump service professionals typically handle installation. At 0.55 pounds, it is a compact, direct-replacement component for failed or degraded capacitors found during routine service calls.

This capacitor is suited for single-phase AC motor applications including well pump motors, HVAC blower motors, air compressors, and similar induction motor loads that require a run capacitor for continuous phase correction. It is appropriate for both residential and light commercial equipment operating on standard 370-volt-rated capacitor circuits. Technicians replacing a failed run capacitor as part of a motor diagnostic or scheduled maintenance will find this a straightforward swap in most standard capacitor brackets and housings.

Key Features

• 45 MFD capacitance for stable phase correction in single-phase motor circuits
• 370 volt AC voltage rating for compatibility with standard residential and light commercial motor circuits
• Rated for 3 HP single-phase motor applications
• Continuous-duty design intended for permanent in-circuit installation
• Compact and lightweight at 0.55 pounds for easy handling in confined equipment spaces

Compatibility

Designed as an OEM-style replacement run capacitor for 3 HP single-phase AC motors requiring a 45 MFD, 370 volt AC rated capacitor.

Installation Notes

Installation should be performed by a qualified HVAC technician, electrician, or pump service professional. Disconnect and lock out all power to the equipment before handling any capacitor, as run capacitors can retain a dangerous charge even after power is removed - discharge the capacitor safely before touching terminals. Verify that the replacement MFD rating and voltage rating match the motor nameplate and original capacitor specifications before installation. Follow all applicable NEC requirements for electrical component replacement.
