Capacitors
Shop start and run capacitors for compatible 230 V single-phase compressor motors and industrial motor applications.
Start & Run Capacitors for Compressor Motors
Start capacitors provide additional starting assistance for compatible single-phase motors, while run capacitors support stable motor operation once running.
The current range includes 40, 50 and 60 µF run capacitors rated at 450 VAC, plus selected 200–315 µF start-capacitor options rated at 250 V.
Match capacitance, voltage rating, capacitor type and physical connection arrangement to the original specification.

Choosing the Correct Capacitor
Use the markings on the original capacitor and the motor information when identifying a replacement.
Capacitance
Match the µF value or specified range.
Voltage Rating
Use a capacitor with the correct required voltage rating.
Start or Run
Confirm the capacitor function.
Physical Fit
Check terminals, diameter, length and mounting arrangement.
Start vs Run Capacitors
Start and run capacitors perform different functions and should not be treated as interchangeable.
- Start capacitors assist motor starting
- Run capacitors remain part of the running circuit where designed
- The motor wiring diagram should determine the required type
- Incorrect values can cause poor starting or motor problems
Replacement Checks
Capacitors can retain electrical charge after the supply is disconnected.
- Safely isolate the electrical supply
- Use competent electrical personnel
- Confirm the original wiring before disconnection
- Verify the replacement specification
- Do not handle or short terminals casually
Frequently Asked Questions
What is the difference between a start and run capacitor?
A start capacitor assists starting, while a run capacitor supports operation during normal running on motors designed to use one.
Can I fit a capacitor with a different µF value?
Only if the motor manufacturer or competent electrical assessment confirms it is appropriate.
What details should I send for identification?
Send the capacitor markings, motor plate, wiring arrangement and clear photographs.
