What does 30+5 uF mean?

It is a dual capacitor with two sections: 30 microfarads for the compressor and 5 microfarads for the condenser fan motor. Each section has its own terminals.

Can I use it to replace a 30+5 uF 370V capacitor?

A 440V rating meets or exceeds a 370V rating, so it is generally a safe upgrade. Match the capacitance values exactly; the voltage rating should be equal or higher.

How do I know which capacitor my system needs?

Read the label on the old capacitor or the unit's wiring diagram. Match both microfarad values and use a voltage rating equal to or above the original.

Does it come with mounting hardware?

No. The capacitor is the metal can only; reuse the existing bracket or strap to secure it.

Is this safe to install myself?

Only if you are comfortable working with line voltage. Shut off power at the breaker and discharge the old capacitor before touching the terminals; otherwise have a technician do it.

Our take on the Supco CD30/5X440R Dual Run Capacitor 30+5uF 440V

The Supco CD30/5X440R is a dual run capacitor for air conditioning and heat pump systems. It packs two capacitances in one round metal can: 30 uF for the compressor and 5 uF for the condenser fan motor, both rated to 440V. That dual-section layout replaces two separate capacitors and simplifies wiring on a service call. It is a common choice for technicians repairing a system with a weak or bulging compressor or fan capacitor.

Pros

Two capacitances in one can: 30 uF and 5 uF
440V rating suits many residential AC and heat pump systems
Round metal can fits standard dual-capacitor mounts
Covers both compressor and fan motor in one part
Straightforward swap for a failed original capacitor

Cons

Must match the original capacitance and voltage exactly
No discharge resistor or mounting strap included
Wrong match can damage the compressor or fan motor
Not for systems needing other microfarad combinations
