|---|---|---|---|---|
| C61 5 Wire Ceiling Fan Capacitor (Formiden) | 4.5, 5, 6 | 250VAC | 5-wire, color-coded | Fans needing multiple speed settings and reliable starts |
| CEILING FAN CAPACITOR CBB61 4.5/6/5uF (YJZR) | 4.5, 6, 5 | 250V AC | 5-wire | Standard replacement for many 5-wire fans |
| YukiHalu CBB61 5+5+5uF Capacitor | 5, 5, 5 | 250-300VAC | 5-wire | Direct replacement for Harbor Breeze, Hunter, and similar fans |
| YukiHalu CBB61 4.5/6/5uF Capacitor | 4.5, 6, 5 | 250-300VAC | 5-wire | Compatible with popular brands and easy wiring |
| YukiHalu 3-Speed Switch with CBB61 Capacitor | 4.5, 6, 5 | 250-300VAC | 5-wire plus pull-chain switch | Integrated speed control and capacitor combo |
C61 5 Wire Ceiling Fan Capacitor 250VAC 4.5μF+5μF+6μF
The Formiden C61 combines 4.5μF, 5μF, and 6μF values in a single unit. It is rated for 250VAC with surge protection up to 350V/300V, supporting multiple fan speed settings and reliable motor starting. Best for homes needing a compact, multi-capacitance replacement in a single component. The 5-wire color-coded system provides clarity during installation. A potential limitation is that some installations may require verification of color mappings for compatibility with older fans.
CEILING FAN CAPACITOR CBB61 4.5/6/5uF 5 WIRE 250V
YJZR’s CBB61 capacitor provides a 4.5uF, 6uF, and 5uF combination with a 5-wire setup. It carries a 250V AC rating suitable for standard ceiling fans and supports both 50/60Hz operation. Best for fans that require a straightforward, ready-to-install three-capacitance solution. The note to verify compatibility with your fan model is important since not all brands use identical wiring colors or tolerance expectations.
YukiHalu CBB61 5+5+5uF 250V 5-Wires
This YukiHalu model uses a symmetric 5uF+5uF+5uF configuration and supports 250V to 300VAC with 50/60Hz compatibility. Its compact size (about 48x38x26 mm) and 5-wire design suit multi-speed fans from Harbor Breeze, Hunter, and other major brands. Choose this if you want uniform capacitance across speeds for consistent performance. A potential limitation is a maximum operating temperature around 85°C, which should be considered in hotter installations.
YukiHalu CBB61 4.5uF+6uF+5uF 5 Wire 250V
This YukiHalu unit provides a 4.5uF, 6uF, and 5uF combination with a five-wire configuration for 250V-300VAC operation. It is designed for compatibility with popular brands and can serve as a direct replacement part. Best for users who want a flexible, 3-capacitor setup in one component. A limitation to note is the maximum operating temperature of 70°C in some listings, which may influence performance in high-heat environments.
YukiHalu Ceiling Fan Pull Chain Switch With CBB61 Capacitor
This option combines a ceiling fan pull chain switch with a CBB61 4.5uF + 6uF + 5uF capacitor in one unit. It provides three speed settings (HIGH, MED, LOW) plus OFF, and an integrated 4-conductor or 5-conductor wiring approach depending on the model. Best for users who want an all-in-one solution for a simple ceiling fan replacement. A caveat is that the included switch and capacitor might not match every existing wiring color scheme, so compatibility should be checked before installation.
Buying Guide
- Capacitance configuration: Look for units offering 4.5μF, 5μF, and 6μF to cover common fan speed ranges. A single multi-capacitance unit can simplify replacements and ensure consistent starting torque.
- Voltage and frequency: Most residential fans use 250VAC ratings and support 50/60Hz. Verify the rating matches your region and fan model.
- Wiring scheme: Five-wire (color-coded) configurations are common. Confirm that your fan’s wiring colors align with the capacitor’s wiring diagram to avoid miswiring.
- Temperature tolerance: Some models specify operating temperatures around 70–85°C. Higher ambient temperatures may affect capacitor longevity, so consider blower or attic conditions.
- Installation complexity: If you need an integrated switch with the capacitor, ensure the pull-chain switch model suits your fan’s control scheme and mounting space.
- Brand and compatibility: While generic replacements exist, matching your fan manufacturer (Harbor Breeze, Hunter, etc.) can reduce troubleshooting after installation.
Frequently Asked Questions
- What does a ceiling fan capacitor do? It provides the phase shift necessary to start the motor and control windings for different speeds.
- Can I use any capacitor for my ceiling fan? Not always. Use a capacitor with the correct μF values, voltage rating, and compatible wiring.
- Is it safe to replace a capacitor myself? Replacing electrical components involves risk. Turn off power, discharge the old unit, and follow the manufacturer’s wiring diagram or consult a professional if unsure.
- Do these capacitors work with all brands? Many are designed for common brands but verify compatibility with your specific model and wiring color conventions.
- Should I replace the switch and capacitor together? If your fan has a worn switch or difficult speed control, combining a switch with a capacitor can improve performance, but ensure compatibility.
- How do I choose between 4.5/6/5μF combinations? 4.5μF is typically for lower speeds, 6μF for higher starting torque, and 5μF balances common speeds; a triple-capacitance unitoffers a broad range.
