Capacitor KEMOT URZ3135 30 µF 450 V for single-phase motors

KEMOT URZ3135 30 µF 450 V is a motor run capacitor designed for use with single-phase electric motors. It provides continuous phase-shifting during operation to stabilise motor torque and improve running characteristics. The capacitor is suitable for use as a direct replacement in motor circuits that require a 30 µF, 450 V run capacitor and is intended for applications where reliable long-term operation under rated voltage is needed.

Advantages

The capacitor offers a precise rated capacitance of 30 µF and a nominal voltage rating of 450 V that supports stable motor performance. It is manufactured to provide low-loss dielectric behaviour for continuous operation, which helps reduce heating and energy waste. Its compact design allows straightforward installation in motor enclosures or control boxes where space is limited. The product is compatible with typical single-phase motor circuits and can be used for both repair and routine replacement tasks.

Suitable for

• Single-phase induction motors used in pumps and fans
• Electric motors in compressors and small machinery
• Replacement of worn or failed run capacitors in motor control circuits
• Retrofit and maintenance tasks in industrial and domestic motor applications

Key specifications

• Rated capacitance: 30 µF
• Nominal voltage: 450 V (AC)
• Type: motor run capacitor for continuous duty
• Application: single-phase motor phase-shifting and running stabilization
• Construction: compact encapsulated unit suitable for installation in motor enclosures

How to use

Before installation, ensure the motor is disconnected from the power supply and verify the required capacitance and voltage rating match the motor manufacturer's specification. Mount the capacitor securely within the motor enclosure or control box, following any mounting orientation guidance from the motor or equipment manufacturer. Connect the capacitor terminals to the motor start/run circuit as indicated in the motor wiring diagram, ensuring tight and corrosion-free connections. After installation, restore power and observe motor operation for correct start-up and running behaviour. If uncertain, consult a qualified electrician or technician to perform the replacement.

Usage recommendations

For reliable service life, avoid ambient temperatures and voltages beyond the capacitor's rated limits and inspect periodically for physical damage or leakage. Replace the capacitor if motor starting or running performance does not improve after fitting, or if visible deterioration is detected. Use appropriate safety precautions when working on electrical equipment, including disconnecting power and discharging capacitors before handling.
