CD60 Motor Starting Capacitor 108-130uF 330V AC Snap-In

The CD60 Motor Starting Capacitor is a dependable aluminum-electrolytic start capacitor built for small-to-mid single-phase AC motors. With a capacitance range of 108–130 µF (MFD) and a 330V AC rating at 50/60 Hz, it delivers the phase-shift surge needed to spin up pool pumps, well pumps, refrigerator compressors, and HVAC fan motors without bogging the supply circuit.[5,14](@ref)

Housed in a rugged bakelite/phenolic resin shell, the capacitor shrugs off heat, shock, and vibration in pump houses, equipment rooms, and outdoor enclosures. Standard snap-in body with 1/4" quick-connect tabs drops straight into existing brackets — a straightforward swap for technicians and DIY repairers.[2,8](@ref)

Key Features

• Capacitance Range: 108–130 µF (MFD), tolerance class varies by build, commonly ±10% to ±20% — confirm the label on the unit you receive.[2,7](@ref)
• Voltage Rating: 330V AC, compatible with 110V–230V single-phase motor systems.
• Dual Frequency: Runs on both 50 Hz and 60 Hz supplies.
• Snap-In Mounting: Standard quick-connect terminals, secures into existing capacitor bracket.
• Durable Shell: Phenolic/bakelite case, good heat and shock resistance.[5,8](@ref)
• Non-Polarized: Either terminal orientation works in the start circuit.
• Intermittent Duty: Engaged only for the few-second start window, then dropped by relay or centrifugal switch.[9,12](@ref)
• PCB-Free: No polychlorinated biphenyls in the construction.[2,4](@ref)

Applications

Direct replacement for start capacitors in the following equipment:

Pool & Water Systems

• Pool pump motors
• Well pumps and jet pumps
• Booster and irrigation pumps

Refrigeration & HVAC

• Refrigerator and freezer compressors
• Window and room air conditioners
• Condenser fan motors and blower assemblies

Household Appliances

• Washing machines
• Small air compressors
• Food disposers and range-hood fans

General Single-Phase Motors

• Any single-phase AC motor using a CD60-type start capacitor in the 108–130 µF range
• Equipment originally fitted with 100–130 µF class start capacitors (verify nameplate first)

When to Replace

• Motor hums but won't start, or needs a manual spin to get going.
• Startup is slow, labored, or the breaker trips when the motor kicks on.
• Case is visibly bulged, cracked, leaking, or the vent disc is popped.[9,15](@ref)
• A capacitance meter reads well outside the labeled range.[9,15](@ref)

Installation & Safety

• This is a motor starting capacitor only — it must be used with a working relay or centrifugal switch that drops it out after startup.[9,12](@ref)
• Never run a start capacitor continuously. A stuck relay or centrifugal switch will cook the cell and bulge the case.[9,12](@ref)
• Lock out and tag the branch circuit. Verify zero voltage at the motor with a known-good tester before touching anything.[3,6](@ref)
• Capacitors store charge after unplug. Bridge the terminals with a 10 kΩ / 5W resistor (or a dedicated discharge tool) for several seconds — do not short with a bare screwdriver.[6,12](@ref)
• Confirm zero volts across the terminals with a meter before handling.[6,9](@ref)
• Photograph the old wiring before disconnecting. Reconnect to the same terminals.
• Match three things: µF range, AC voltage rating (330V AC or higher), and physical dimensions/bracket style.[2,15](@ref)
• Voltage can be equal to or greater than original, never lower.[2,12](@ref)
• Not sure? Call a licensed electrician. Start capacitors hold a painful — sometimes dangerous — charge.
