Motor Run Capacitor XTREME 450VAC 3338 — 450 VAC motor capacitor for AC motors

XTREME 450VAC 3338 is a motor run capacitor designed for alternating-current (AC) motors requiring a 450 VAC rated run capacitor. It supplies reactive power to support motor starting and continuous operation, helps improve power factor and reduces voltage fluctuations under varying load. The capacitor is intended for installation in motor circuits of pumps, fans, compressors and similar equipment where a 450 VAC run capacitor specification is required.

Advantages

The capacitor offers stable capacitance under normal operating temperatures and is engineered for continuous duty in AC motor circuits. Its 450 VAC rating makes it suitable for higher-voltage single-phase and certain three-phase motor applications that require an external run capacitor. The design focuses on reliable reactive power delivery, reduced electrical stress on motor windings, and smoother motor operation over a range of loads.

Suitable for

• Pumps driven by AC motors that specify a 450 VAC run capacitor
• HVAC and ventilation fans requiring run capacitors for motor efficiency
• Compressors and refrigeration motors needing reliable continuous-capacitance support
• Industrial or commercial motor-driven equipment where a 450 VAC rating is specified

Key specifications

• Rated voltage: 450 VAC suitable for motor run applications
• Type: motor run capacitor for continuous operation
• Function: reactive power support to improve power factor and stabilize motor load
• Application environment: designed for use with pumps, fans, compressors and similar AC motor equipment

How to use

Install the capacitor in accordance with the motor and equipment wiring diagram, observing correct polarity and connection points where applicable. Ensure the motor is powered off and isolated before making any connections. Mount the capacitor securely in a location that allows adequate ventilation and protects it from excessive vibration, moisture and heat. Verify that the motor circuit voltage matches the capacitor rating and that the capacitor’s capacitance value is appropriate for the motor as specified by the motor or equipment manufacturer.

Usage recommendations

Before installation, consult the motor nameplate and equipment documentation to confirm compatibility with a 450 VAC run capacitor. Use appropriate protective devices such as fuses or circuit breakers, and follow local electrical codes. Periodically inspect the capacitor for signs of physical damage, swelling, leakage or excessive temperature rise and replace if abnormalities are found.
