Motor Run Capacitor – CBB65
-
Capacitance: 45 µF (±5%)
-
Voltage: 450V AC
-
Frequency: 50/60 Hz
-
Protection: SH (Self-healing)
-
Standard: EN60252-1
-
Terminals: 2-pin
-
Brand marking: SHENGE (same family as the 40 µF one)
Typical applications:
-
Compressor run capacitor
-
High-load outdoor AC units
-
Common in 2.0 – 3.0 HP systems (brand/design dependent)
Replacement rules (very important ⚠️):
-
µF must match exactly → 45 µF
-
Voltage 450V or higher only
-
Must be run capacitor (CBB65), oil-filled metal can
-
Do NOT replace with 40 µF or 50 µF unless manufacturer allows
Quick ladder of what you showed (for clarity):
-
12.5 µF → small fan motor
-
16 µF → medium motor
-
20 µF → mid compressor
-
30 µF → larger compressor
-
40 µF → heavy compressor
-
45 µF → very heavy compressor load
