AP APPLI PARTS Motor Start Capacitor 540–648 µF 110–125 VAC — CD60 UL‑Certified, PCB‑Free, 1/4" Quick‑Connect

The AP APPLI PARTS CON-540-110 is a CD60-rated motor start capacitor delivering 540–648 µF at 110–125 VAC to give single‑phase motors the brief torque boost they need to start reliably.

This heavy‑duty electrolytic start capacitor is built for intermittent duty in motor start circuits and is designed to replace units with the same capacitance and voltage ratings. It meets UL certification standards, is PCB‑free, and is suitable for common applications such as water pumps, compressors, pool pumps and other equipment that require a high starting torque for a few seconds. Before installing, confirm the physical dimensions and terminal type match the unit being replaced.

What electrical specs should I check before buying this capacitor?

Match capacitance, operating voltage and terminal type to the original part. This capacitor supplies a high µF value for starting and is rated for 110–125 VAC with a 1/4 inch male quick‑connect terminal.

• Capacitance: 540–648 microfarads (µF)
• Voltage: 110–125 VAC operating range
• Tolerance: ±20% of rated capacity
• Terminal: 1/4 inch male quick‑connect

How does this capacitor perform in different environments and temperatures?

The CON-540-110 is engineered to operate across a wide temperature range and at standard motor line frequencies, making it suitable for many indoor and covered outdoor installations. It’s built for short, high‑energy pulses during motor start and is not intended for continuous run duty.

• Operating temperature: -40°F to +149°F (-40°C to +65°C)
• Frequency compatibility: 50/60 Hz
• Duty: Intermittent motor start (short duration use)
• Construction: Electrolytic, non‑polarized CD60 type

Which devices and systems commonly use this start capacitor?

This capacitor is suitable for a wide array of motorized equipment that requires a start boost. It replaces many OEM units with the same electrical and mechanical fit, but always verify physical size and mounting before replacing.

• Water pumps and pool pump motors
• Air compressors and workshop machinery (e.g., table saws)
• HVAC fan motors and small industrial motors
• General single‑phase motor start circuits

Is this capacitor safe and certified for replacement use?

Yes—the CON-540-110 is UL‑certified (E479187) and manufactured without PCB materials. It’s built to provide reliable start performance when installed correctly and used within its rated specifications.

• Certification: UL E479187
• Type: CD60 electrolytic, PCB‑free
• Design: Non‑polarized for single‑phase motor start use
• Recommended: Confirm dimensions (1.75 in wide, 3.38 in height) before replacing

Who this is for: Installers, maintenance technicians, and DIYers replacing or upgrading motor start capacitors in single‑phase equipment will find the AP APPLI PARTS CON-540-110 a direct and dependable option when the electrical ratings, terminal type, and physical dimensions match their application. It’s intended for intermittent start use—if your motor requires a run capacitor or different duty cycle, choose a model specified for continuous operation.
