45+5 MFD Dual Run Capacitor 370/440V for AC or Heat Pump - 1 Year Warranty

MAXRUN 45/5 MFD 370/440 VOLT CAPACITOR SPECIFICATIONS

When it comes to the MaxRun 45/5 MFD 370/440 Volt Capacitor, it's important to check the specifications carefully. This capacitor measures 2 3/8" in diameter and 4" in height. It is rated for 440 Volts, allowing it to function at either 370 or 440 VAC. It can operate in temperatures ranging from -40 C. to +70 C. Furthermore, it is safety rated at 10,000 AFC.

This dual run capacitor combines two capacitors in one unit, making it suitable for powering both a compressor motor and a fan motor. It features three terminals labeled "Herm" for the compressor motor, "Fan" for the fan, and "C" for the common line.

Capacitors play a crucial role in the operation of electric motors that power compressors and condensers in air conditioning systems. Similar to a battery, the capacitor stores and releases a large charge quickly, providing the motor with the necessary spin to start and run efficiently.

As capacitors age, they tend to lose their ability to hold a charge and weaken over time. When a capacitor becomes weaker, the motor may operate louder and slower. Timely replacement of the capacitor is essential to prolonging the life of the motor and preventing motor failure.

When replacing a capacitor, safety precautions must be taken, including turning off the power to the air conditioning unit and discharging any stored charge using a screwdriver. It is recommended to measure the height and width of the old capacitor to ensure a correct fit with the replacement unit. Keeping a spare capacitor on hand is also advisable for future use.

The MaxRun 45/5 MFD 370/440 Volt Capacitor is built to the highest standards, meeting EIA-456-A and IEC 60252-1:2001 specifications. With its ability to run both a compressor and fan at 370 or 440 volts, and engineered for safety with a 10,000 AFC anti-explosion pressure switch and no PBA's, it offers ease of replacement and reliable performance. Simply turn off the power, mark and transfer the wires to the new capacitor, replace it, and turn the power back on for continued operation.
