Motor Run Capacitor – CBB65A
-
Capacitance: 50 µF (±5%)
-
Voltage: 450V AC
-
Frequency: 50/60 Hz
-
Type: Oil-filled, metal can
-
Protection: SH (Self-healing)
-
Terminals: 2-pin
-
Brand marking: ENG / SHENGE family
Typical applications:
-
Compressor run capacitor
-
Heavy-duty outdoor AC units
-
Commonly used in 2.5 – 3.0 HP systems (depends on brand & compressor)
Replacement rules (very important ⚠️):
-
µF must match exactly → 50 µF
-
Voltage 450V or higher only
-
Must be run capacitor (CBB65/CBB65A)
-
Do NOT replace with 45 µF or 55 µF unless manufacturer explicitly allows
Full ladder from what you showed (for reference):
-
12.5 µF → small fan motor
-
16 µF → medium motor
-
20 µF → mid compressor
-
30 µF → large compressor
-
40 µF → heavy compressor
-
45 µF → very heavy load
-
50 µF → highest compressor load
