How it works and how to install it
The start capacitor provides an additional electrical impulse when the electric motor starts, creating a phase shift necessary for generating the starting torque. It connects to the motor terminals via the 4 male spade terminals, and the metal screw ensures mounting on the equipment frame or a separate bracket. After connecting the terminals according to the motor diagram and mechanical fastening, the capacitor automatically activates with each equipment start.
Frequently asked questions
How do I know if this capacitor is suitable for my motor?
Check the motor label — the capacitance (140uF) and voltage (450V) must match the original specifications. If the motor starts with difficulty or does not start at all, a faulty capacitor is a common cause.
How long does it last before replacement?
At a nominal voltage of 450V, it is designed for 3000 hours of effective operation (class C). The actual duration depends on the number of starts and temperature conditions, generally 3-5 years in domestic applications.
Can I use the capacitor at sub-zero temperatures?
Yes, it operates between -40°C and +85°C, making it suitable for heat pumps or equipment mounted outdoors.
