CBB60 45µF 250VAC Motor Start-Run Capacitor – for Washer Pumps

This CBB60 45µF (45MFD) 250VAC capacitor uses metallized polypropylene film in a flame-retardant case with 2-wire leads, built for start-run duty in single-phase AC motors. A direct replacement for washing machine drain pump motors and small appliance motors specifying 45µF. Extends our CBB60 washer-pump lineup to cover the heaviest OEM-specified starting torque requirements.

Key Features

• ✅ Type: CBB60 metallized polypropylene film capacitor
• ✅ Capacitance: 45µF (45MFD)
• ✅ Rated Voltage: 250V AC
• ✅ Duty: Motor start-run (continuous run with start assist)
• ✅ Leads: 2-wire outlet (tinned copper, non-polarized)
• ✅ Self-healing dielectric – recovers from micro-breakdown
• ✅ Low dissipation factor – runs cool under load
• ✅ Flame-retardant molded case (UL94-V0 class typical)
• ✅ RoHS compliant, no PCB

Specifications

Applications

• Washing machine drain pump motors (45µF spec)
• Heavy-duty washer spin / circulation pump motors
• Dishwasher drain pump motors with maximum starting load
• Small water pump & fountain pump motors (250V class)
• Single-phase AC induction motors requiring 45µF start-run assist
• Compactor / small appliance motors with stiff starting loads

20 / 30 / 35 / 40 / 45µF – Which Do You Need?

• 20µF: Most common – standard front-load washer drain pumps.
• 30µF: Larger pumps, some top-load and commercial units.
• 35µF: Heavy-duty pumps, pump+spin combos.
• 40µF: Maximum torque – large impellers, heavily loaded pumps.
• 45µF: Top of the range – OEM-spec'd for the heaviest pump motors or motors that previously failed with lower values.
• Rule: Always read the old capacitor's printed label. Using the wrong µF changes motor torque characteristics and can cause overheating or failure to start.

Wiring & Replacement

• Non-polarized: Either wire goes to either motor terminal per the appliance schematic.
• Power off + discharge: Unplug the washer, discharge old cap before touching leads.
• Match values: Replace with 45µF ±5% and 250VAC or higher. Never substitute a lower voltage class.
• Symptom check: Pump hums but won't spin = classic failed run cap. Swap before condemning the motor.
• Space check: 45µF is the largest in this series – verify clearance in the original mounting location before ordering.

Why This Cap

When a washer pump calls for 45µF, it's the manufacturer's way of saying "this motor needs maximum starting assistance." Whether it's a high-head drain pump, a large-capacity machine with a bigger impeller, or a motor that's been borderline with 35–40µF, this CBB60 45µF 250VAC delivers the required torque with low-loss PP film that stays cool through repeated high-current starts. Self-healing dielectric handles occasional overstress, and the 2-wire lead-out drops straight into existing connectors. If your old cap reads 45µF, this is your part – the top of our CBB60 washer-pump range.
