30+5 µF Dual Run Capacitor, 370/440V CBB65 Round HVAC Capacitor with Labeled HERM, FAN and C Terminals
A 30+5 µF dual run capacitor powers compatible compressor and condenser-fan motors from one compact round component. The three top terminal groups are clearly labeled HERM for the compressor, FAN for the fan motor and C for common, helping a qualified technician reproduce the documented wiring layout during replacement.
Rated for 370/440V AC at 50/60Hz, the metallized polypropylene CBB65 capacitor operates from -40°C to 70°C and includes a listed 10,000 AFC safety rating. The 1.97-inch diameter and 3.94-inch height fit many compatible HVAC compartments. It may replace an oval unit only when both capacitance values, voltage, terminal arrangement and mounting clearance match.

Frequently Asked Questions
Which terminal connects to each HVAC component?
The top groups are labeled HERM or H for the compressor FAN or F for the fan motor and C for the common line. Follow the equipment wiring diagram.
Can this round capacitor replace an oval one?
Yes only if 30+5 MFD voltage terminals and available mounting space all match the equipment requirements. Shape alone does not determine compatibility.
Is the capacitor rated for both 370V and 440V systems?
It carries a 370/440V AC rating. Still confirm the original capacitance and every equipment specification before replacement.
What is its operating temperature range?
The listed range is -40°C to 70°C or -104°F to 158°F for compatible 50/60Hz HVAC motor applications.
