CBB60 Motor Run Capacitor 450VAC – 1µF to 3.5µF, Quick Connect Terminal, 7 Values

The CBB60 Motor Run Capacitor series delivers reliable continuous-duty phase-shift support for single-phase AC motors. Rated 450VAC 50/60Hz with metallized polypropylene film construction, these capacitors are built for pumps, compressors, small industrial motors, and HVAC auxiliary units. Available in 7 capacitance values from 1µF to 3.5µF, all sharing the same compact housing and standard quick-connect terminals.

Note: CBB60 is a RUN capacitor (continuous operation). Not for intermittent start-only duty — for start applications, see CD60 series.

CBB60 vs CD60 vs CBB61 — Quick Guide

Series	Duty	Terminal	Voltage Range	Best For
CBB60	Continuous Run	Quick-Connect Spade	250V–500VAC	Pumps, compressors, motors
CBB61	Continuous Run	Wire Leads	250V–500VAC	Ceiling fans, exhaust fans
CD60	Intermittent Start	Spade / Wire Leads	110V–330VAC	Motor starting (brief duty)

Selection Guide

• Match µF exactly — within ±5% is acceptable. Oversizing run capacitance can overheat the motor winding.
• Voltage rating: 450VAC is safe for 230V and 115V single-phase motors (derated for margin).
• Physical fit: Check case shape (oval/round), mounting hole, and terminal orientation before ordering.
• Terminal size: Confirm 6.3mm spade connectors are available in your installation.

Installation & Safety

• Disconnect all power and verify motor is de-energized before servicing.
• Discharge the old capacitor — run capacitors can retain charge.
• Connect wires to spade terminals: push-on firmly, ensure no bare conductor exposed.
• Secure the capacitor to the motor bracket or housing using the provided mounting provision.
• Do not pinch wires between case and motor housing.
• Replace with same µF and equal-or-higher voltage rating.
