Capacitor XTREME 1 µF 450 VAC motor (MPN 3331#)

Motor capacitor XTREME 1 µF 450 VAC is a single-function component designed for AC motors and starting circuits. With a rated capacitance of 1 microfarad and a working voltage of 450 VAC, this capacitor provides phase shift, noise suppression and improved stability during motor start and normal operation. It is suitable for use in household and light industrial equipment such as fans, blowers and small pumps where a compact run or start capacitor is required.

Advantages

The capacitor offers a precise rated capacitance of 1 µF and a high AC working voltage of 450 V to match common motor starting and run requirements. Its construction is optimized for stable performance under alternating voltage conditions, reducing electrical noise and helping maintain consistent motor torque at low and starting speeds. The compact form factor allows installation in confined motor housings or control boxes.

Suitable for

• Single-phase motors requiring phase-shift or run/start support
• Fans and ventilation units
• Small pumps and compressors
• General household and light industrial appliances

Key specifications

• Capacitance: 1 µF
• Rated AC voltage: 450 VAC
• Type: motor/run or start capacitor (single-function)
• Intended use: AC motor phase shift and noise suppression
• Typical mounting: in motor housing or control enclosure

How to use

Install the capacitor according to the motor manufacturer’s wiring diagram, ensuring the power is disconnected before handling. Connect the capacitor between the appropriate motor terminals for start or run configuration, observing correct polarity if specified by the motor circuit (note that many AC capacitors are non-polarized). Secure the capacitor mechanically to prevent vibration and verify connections are tight. After installation, perform a test run to confirm proper motor starting and stable operation.

Usage recommendations

Verify compatibility with the motor’s required capacitance and voltage; do not exceed the specified working voltage. Replace failed or aged capacitors with an equivalent 1 µF 450 VAC unit to maintain motor performance and avoid increased current draw or starting failures. For safety, perform insulation and continuity checks and follow local electrical regulations when installing or replacing the capacitor.
