MAXRUN 45+5 MFD Dual Run Capacitor for AC or Heat Pump

MAXRUN 45/5 MFD 370/440 VOLT CAPACITOR SPECIFICATIONS:

The capacitor measures 2 3/8" in diameter and 4" in height. It is important to carefully check the specifications to ensure the correct fit.

This capacitor is rated for 440 Volts, meaning it can operate at both 370 and 440 VAC. It is designed to function within a temperature range of -40°C to +70°C.

Furthermore, the capacitor is safety-rated at 10,000 AFC, providing reliable and secure performance.

The 45/5 capacitor is a dual run capacitor, combining two capacitors into a single unit. It powers both the compressor motor and the fan motor, and has three terminals on the top: "Herm" for the compressor motor, "Fan" for the fan, and "C" for the common line.

Run capacitors play a crucial role in the operation of electric motors that power air conditioning compressors and condensers. They store and release large charges quickly, providing the necessary spin for the motors to start and run correctly.

As air conditioning capacitors age, they lose their ability to hold a charge, leading to weaker performance. This can result in louder motors and slower operation. Replacing the capacitor before it weakens significantly can extend the lifespan of the motor.

If the capacitor becomes too weak to start the motor, the motor may short out. Therefore, timely replacement of the capacitor is essential for proper air conditioning maintenance.

When replacing a capacitor, it is important to turn off the power to the air conditioning unit and discharge any stored charge by placing a screwdriver between the terminals of the capacitor. MaxRun Capacitors are designed to be a direct fit, but it is recommended to measure the height and width of the old capacitor to ensure a perfect match.

This MAXRUN 45/5 MFD 370/440 Volt Capacitor is designed and built to the highest standards, meeting EIA-456-A and IEC 60252-1:2001 specifications. It is engineered for safety, featuring a 10,000 AFC anti-explosion pressure switch and no PBAs (Printed Board Assemblies) used in its construction.

Replacing the capacitor is a straightforward process. First, turn off the power, mark the wires, and move them to the new capacitor. Then, replace the old capacitor with the new one and turn the power back on.
