Capacitor Lamex LXKON10 40 µF 450 V AC KNM, motor/start capacitor

The Lamex LXKON10 40 µF 450 V AC motor/start capacitor is designed for use in AC-driven equipment where reliable phase shift and stable capacitance are required. It is suitable for improving starting torque, assisting single-phase motors, and providing power-factor correction in systems such as pumps, compressors and HVAC units. The capacitor is part of a family intended for motor start/run and general AC applications and is specified for continuous or intermittent use consistent with motor starting and operation demands.

Advantages

This 40 µF capacitor provides stable capacitance under typical operating conditions, helping to maintain consistent motor performance and smoother starts. Its 450 V AC rating makes it compatible with a wide range of single-phase systems. The design is intended for replacement or installation in systems that require a motor/start capacitor with these electrical characteristics, offering straightforward substitution where the same capacitance and voltage rating are specified.

Suitable for

• Pumps and circulation systems driven by single-phase motors
• Compressors requiring start or run phase shifting
• HVAC blowers and fan motors
• General single-phase motor repair and maintenance

When it may not be suitable

This capacitor is specified for AC motor start/run and general AC applications. It may not be suitable for DC circuits, electronic timing circuits, or applications that require very low loss (high Q) or specialized dielectric properties not typical of motor capacitors. It is also not appropriate where a different capacitance value, voltage rating, or form factor is mandated by the equipment manufacturer.

Key specifications

• Capacitance: 40 µF
• Rated voltage: 450 V AC
• Intended application: Motor start/run and general AC use
• Typical uses: Phase shifting for single-phase motors, power-factor support

How to use

Install the capacitor according to the motor or equipment wiring diagram, ensuring power is disconnected before any work is performed. Connect the capacitor between the designated start/run terminals or as specified by the equipment manufacturer. Ensure secure mounting and proper terminal connection to prevent vibration-induced loosening. After installation, check the motor for correct starting behavior and verify there are no unusual noises or overheating. Use appropriate personal protective equipment and follow local electrical safety standards.

What to consider before purchase

• Ensure the required capacitance is 40 µF for your motor or circuit
• Confirm your system operates at or below 450 V AC rating
• Verify the physical form factor and terminal type fit the installation location
• Check whether the application requires a motor-run versus motor-start specific capacitor type

Usage recommendations

For reliable results, replace capacitors with units matching capacitance and voltage ratings and follow the equipment manufacturer's maintenance intervals. If in doubt about compatibility or safety, consult a qualified electrician or service technician before installation.
