Description
Overview:
This capacitor is a replacement motor capacitor for pre-1999 Belle compact mixers and similar single-phase machines. Rated at 30 F, it supports reliable starting and smooth running of induction motors typically found in the Minimix 150 and Maxi 140. The unit has a tough, sealed plastic body designed to cope with vibration, dust and moisture common on building sites and in workshops. It replaces CMS21 and corresponds to manufacturer part number 231 572. Suitable for equipment within a 2600-3000 W power range, it helps restore correct motor performance when the original capacitor has weakened or failed. Use it to maintain consistent mixing, pumping or lighting output on site and to reduce nuisance tripping or motor humming caused by a tired capacitor.
Key Features:
- 30 F capacitance for dependable motor starting and smooth running on single-phase equipment
- Suitable for machines in the 2600-3000 W range to match typical compact mixer motors
- Direct replacement for CMS21 for pre-1999 Belle applications
- Robust, sealed plastic construction for durability in dusty and damp environments
- Compact cylindrical form factor for easy placement in tight housings
- Helps reduce motor stalling, overheating and poor torque caused by a failing capacitor
- Straightforward swap-in fit for maintenance or repair without complex adjustments
- Supports consistent performance of the Belle Minimix 150 and Maxi 140
- Reliable choice for site use where vibration and temperature changes are common
- Manufacturer reference 231 572 for clear identification
Typical Applications:
Restoring start/run function on single-phase motors in small cement mixers, pressure washers, tower lights, garden shredders and similar equipment. Ideal for pre-1999 Belle compact mixers where consistent torque, smoother running and reliable restarts are required in daily site or workshop use.
Also known as:
Motor capacitor, motor run capacitor, motor start capacitor, condenser, start/run capacitor, phase-shift capacitor, 30 F motor capacitor.
