Run Capacitor

Category Overview

Run capacitors are critical components that remain permanently in the circuit and create the running phase of the motor in many appliances, from air conditioner fan motors to combi boiler circulation pumps and from washing machine motors to extractor and ventilation fans. Unlike the start capacitor, it remains in the circuit throughout the running time and ensures that the motor rotates efficiently, quietly and without vibration. In this section under the Yedepa.com Capacitors parent category, you can find run capacitors in the microfarad values most frequently needed by technicians, with 400V and 450V operating voltages, plastic bodies and 4 terminals. All products are kept ready in stock, and orders are handed over to the courier quickly.

Products You Can Find in This Category

The category has a wide range of microfarad values to meet different capacitance needs. It is possible to find a model suitable for every application, from low-value small fans to combi boiler circulation pumps and more powerful motors. Some of the featured products are:

• 2 µF Run Capacitor – Plastic body, 4 terminals, 400V; ideal for small fan and extractor motors.
• 3 µF Run Capacitor – 400V plastic body, frequently chosen for air conditioner indoor unit fan motors.
• 450V 2.5 µF Combi Boiler Circulation Pump Capacitor – Plastic body; direct replacement for the classic failure point in combi boiler pumps.
• 5 µF Run Capacitor – 400V, 4 terminals; common value for medium-power fan and pump motors.
• 14 µF Run Capacitor – 400V, 4-terminal plastic body; capacitance level used in more powerful motors.

Selection Criteria and Tips

Choosing the right capacitor directly affects the life and efficiency of the motor. A capacitor with the wrong microfarad value can cause the motor to overheat, trip the fuse and even burn out the winding. The basic criteria to consider when choosing:

• Microfarad (µF) value: Must be exactly the same as the value written on the motor label or on the old capacitor.
• Operating voltage: 400V and 450V models are the most common; a capacitor with a lower voltage must never be used.
• Terminal type: 4-terminal (faston) models make cable connection easier and shorten service time.
• Body construction: Plastic-bodied capacitors are light, heat-resistant and long-lasting.
• Place of application: The choice of capacitance varies according to the appliance, such as combi boiler pump, air conditioner fan or washing machine motor.

When in doubt, the safest way is to read the value on the faulty capacitor; if the label is unreadable, it is recommended to refer to the appliance's service catalogue.
