Capacitors and Thermal Overload Relays
Capacitors for electric motors and pumps
Capacitors are essential components for single phase electric motors and pumps, helping them start and run efficiently. At SOCO, we stock a wide range of motor run and motor start capacitors, along with accessories like brackets, terminal covers and stud mounts, so you can quickly replace faulty capacitors and avoid downtime.
With ready stock and fast shipping, replacements are available when you need them either via local pick up or overnight delivery. Our team can also help you identify the right capacitor for your motor or pump.
Motor Run Capacitors

- Stud Mount: 2 µF up to 70 µF, 450V AC
- Permanent Stud Mount (M8 thread): 12 µF up to 40 µF, 450V AC
- Standard: 2 µF up to 70 µF, 450V AC
Lead Terminals:
- Stud Mount: 2 µF up to 70 µF, 450V AC
- Permanent Stud Mount (M8 thread): 4 µF up to 60 µF, 450V AC
- Standard: 2 µF up to 70 µF, 450V AC
Motor Start Capacitors
Spade Terminals:
- 64-77 µF up to 340-408 µF, 250V AC

Quick Tips for Replacement
To help us quickly find the right replacement the key information we need is:
- Microfarads (µF)
- Capacitor type (motor run or motor start)
- Terminal type (spade or lead)
You can take a clear photo of your capacitor showing this info and send it to sales@soco.co.nz, or bring the capacitor into us at 471 Tremaine Avenue, Palmerston North.
Thermal overload relay switches
Keep machinery running and protect electric motors against overloads and phase failure with a thermal overload relay. Available off the shelf.

Have stock of your own
Utilise our off the shelf range of motor run and motor start capacitors and thermal overload relays with pick up or overnight shipping. Or have stock of your own, so you have them when you need them. Capacitors and overload swtiches can fail at any time.
