XL³ Enclosure for safe and standard and complaint installation. Continuous and well distributed energy is the need of the hour today. With its extensive range of Acbs, MCCBs the Legrand offer meets your quality standards and provides real freedom and simplicity of installation together with acknowledged reliability.

Distribution not only makes for easy assembly, but also enables you to save time while installing them as well as during maintenance and extension operation.

Beside their easy mounting and connection, strength and good continuity of operation, different types of electronic protection units allow precise adjustment of different limits and display of electrical values.

The Value of the power factor of a load will range from 0 to 1.

The closer the power factor approaches to unity, the greater the benefit to the consumer and supplier.

Advantages of improving the power factor

• Reduction in the cost of electricity.
• Technical and economical optimization by allowing the usage of smaller transformers, switchgear and cables.
• Reduction of power losses and voltage drop in an installation.

At low voltage, compensation is provided by

• Fixed-value capacitor.
• Automatically-controlled stepped bank of capacitors which allow continuous adjustment as and when the loading of the installation changes.

A bank of capacitors is divided into a number of sections, each of which is controlled by a contactor.

Capacitors

• Improving the power factor of an installation requires a bank of capacitors which acts as a source of reactive energy. This arrangement is said to provide reactive energy compensation.

Detuned Reactors

• Designed to protect the capacitors against harmonics and avoid parallel resonance and amplification of harmonics flowing on the network.

Power Factor Controller

• Controls the connection and disconnection of the steps in order to maintain the target power factor.
