Know before you buy
Yes, you can generally replace a 440V capacitor with a 370V version, but you should never replace a 370V capacitor with a lower voltage rating. The 370V rating indicates the maximum voltage the capacitor can handle safely.
No, this is a non-polarized capacitor, meaning it does not have a positive or negative terminal. You can connect the wires to either terminal without affecting performance.
It is important to match the MFD rating specified by your motor's manufacturer. Using a capacitor with a significantly different MFD rating can cause the motor to overheat, run inefficiently, or fail to start properly.
Common signs include a motor that hums but won't start, a motor that runs slower than usual, or a capacitor that appears physically swollen or leaking. If you have a multimeter with a capacitance setting, you can also test the unit to see if it still holds the rated 35 MFD.
Yes, this run capacitor is designed for standard electrical equipment and motor applications. However, ensure it is housed within a protective, weather-resistant enclosure if the motor is located outdoors.
