SOURCE1 dt-4jr7545u Dual Run Capacitor 45/7.5 Mfd 370/440V Round

Product Description

The SOURCE1 dt-4jr7545u is a dual run capacitor rated at 45/7.5 MFD and 370/440 volts AC. It is designed for use in residential and commercial HVAC systems, providing the continuous electrical boost that compressor and fan motors need to run efficiently. Run capacitors stay energized throughout the full motor operating cycle. They maintain a steady phase shift in the motor windings, which keeps the motor running smoothly and at the correct torque. Without a properly functioning run capacitor, motors draw excess current, overheat, and fail prematurely. The dual configuration means this single capacitor serves two motor loads at once, typically the compressor and the condenser fan motor. This simplifies replacement and reduces the number of components inside the electrical panel. The 45 MFD side typically supports the compressor, while the 7.5 MFD side supports the fan motor. The 370/440 volt rating makes this capacitor compatible with a wide range of single-phase AC equipment found in central air conditioners, heat pumps, and packaged rooftop units. The oil-filled construction provides stable capacitance over a wide temperature range, from -40 to 70 degrees Celsius. This makes the capacitor reliable in both extreme cold during low-demand periods and extreme heat during peak summer operation. The round shape is the standard form factor for most residential and light commercial condensing units. Quick connect terminals allow for fast, tool-free wiring connections, which reduces labor time during service calls. The 5 percent tolerance rating ensures consistent capacitance values and predictable motor performance. HVAC technicians rely on direct-fit dual run capacitors like the SOURCE1 dt-4jr7545u to restore system operation quickly and confidently. This capacitor is a direct replacement for failed or degraded dual run capacitors in York and compatible HVAC equipment.
