## Summary description

KEMOT URZ3137 is a motor-run capacitor rated 40 µF and 450 V designed for single-phase electric motors. It provides continuous reactive power compensation to improve motor starting and running performance. Suitable for replacing or installing in fans, compressors, pumps and other single-phase motor applications that require a 40 µF/450 V run capacitor.

## Long description

KEMOT URZ3137 40 µF 450 V is a motor-run capacitor intended for continuous use with single-phase electric motors. Designed to provide reactive power compensation during motor operation, this run capacitor helps stabilize voltage and phase shift in the motor circuit to support reliable starting and steady running. It is suitable for applications such as fans, compressors, pumps and other single-phase equipment that require a 40 µF, 450 V run capacitor.
Advantages
The capacitor is manufactured for continuous duty and rated for operation at 450 V, offering stable capacitance of 40 µF under normal operating conditions. Its construction is optimized for motor-run applications where sustained reactive power delivery is required. The component helps reduce electrical stress on windings by improving phase balance and can contribute to smoother motor operation and more consistent RPM under load.
Suitable for
 Replacement of 40 µF/450 V motor-run capacitors in single-phase fans
 Single-phase compressors used in refrigeration or air systems
 Pumps driven by single-phase motors in domestic or light industrial settings
 Other single-phase motor-driven equipment requiring continuous run capacitors
Key specifications
 Capacitance: 40 µF
 Rated voltage: 450 V AC
 Type: motor-run capacitor for continuous duty
 Application: single-phase motor reactive power compensation
How to use
Before installation, disconnect power to the motor and verify that capacitors are fully discharged. Mount the capacitor in a dry, vibration-minimized location with adequate ventilation and secure electrical connections according to the motor wiring diagram. Observe correct polarity and terminal identification where applicable, and ensure the replacement matches the original capacitor's capacitance and voltage ratings. After installation, restore power and monitor motor performance, checking for stable starting and running behavior.
Usage recommendations
Use this 40 µF 450 V run capacitor only in motors and circuits specified for its ratings. Regularly inspect for signs of aging, overheating, bulging or leakage and replace if any deterioration is detected. For safety, follow local electrical codes and consult a qualified electrician for installation and maintenance.
