Motor Run Capacitor – CBB65

• Capacitance: 55 µF ±5%

• Voltage: 450V AC

• Frequency: 50/60 Hz

• Dielectric: Vegetable oil (oil-filled)

• Protection class: S2 / Self-healing

• Temperature rating: 40/85/21

• Terminals: 2-pin

• Brand: Mascotop

Typical applications:

• Compressor run capacitor

• High-capacity outdoor AC units

• Often used in 3.0 HP and above systems (depends on compressor design)

Replacement rules (very important ⚠️):

• µF must match exactly → 55 µF

• Voltage 450V or higher only

• Must be run capacitor (CBB65), metal can

• Do NOT replace with 50 µF or 60 µF unless manufacturer allows

Quick ladder recap (from smallest → largest you showed):

12.5 → 16 → 20 → 30 → 40 → 45 → 50 → 55 µF
