30µF · 450VAC · CBB60 Motor Run Capacitor

What you're buying

A 30µF 450VAC motor run capacitor in the CBB60 body, designed to run continuously while the motor is operating. This listing covers every terminal style (Lug Terminal or Core Lead): choose yours from the Terminal dropdown above to match how your old capacitor's wires come out. The µF and voltage are identical across all of them: only the connection differs.

µF (capacitance) and voltage are the two specs that matter for fitment. Match the µF on the old capacitor's label, within ±5%: too low and the motor won't start, too high and it will run hot. Voltage must be equal or higher than the original; you can safely substitute a 450VAC unit for any motor specced at 450V or below, but never the other way around.

Commonly used for

• Compressors & air tools: typical range 25-80µF · 370/450V
• HVAC & heat pumps: typical range 5-80µF · 370/440V
• Pool & spa pumps: typical range 15-60µF · 370/450V
• Well & domestic pumps: typical range 8-70µF · 450V

Which terminal do I need?

This 30µF cap is sold as one listing with 2 terminal styles (Lug Terminal or Core Lead), selectable from the dropdown above: the µF and voltage are identical across all of them, only the connection differs. Lug Terminal: 6.3mm quick-connect male tabs that take push-on female spade receptacles. No soldering, just push on. Core Lead: a central threaded stud for bracket mounting plus lead-out wires. Pick the style that matches how your old capacitor connected, or fit a spade adapter to convert between them.

Construction

• metallised polypropylene film, oval/rectangular plastic case with wire leads or spade terminals: the most common motor-run body in NZ.
• Polypropylene film, self-healing: small punctures clear without short-circuit.
• ±5% capacitance tolerance · 50/60 Hz · 70°C max ambient operating temperature.
• Mounting: Wire leads or spade terminals.
• Terminal options: Lug Terminal or Core Lead. Select on the page.

What not to buy this for

• Don't buy this for a motor-start application (compressor relay, pump priming). Motor-start caps usually have a much higher µF for short bursts and a CD60 body. This unit is rated for continuous duty, not the high inrush of a start cap.
• Don't buy by µF alone: physical size needs to fit the housing, and the terminal style (pick Lug Terminal or Core Lead to match your wiring) needs to match your existing wiring or you'll need an adapter.
