Overview

PX (F) distribution box is a kind of beautiful, novel and innovative, which is continuously developed and improved by our company to meet the requirements of continuous updating of low-voltage electrical products and users to put forward various new requirements for terminal distribution boxes in low-voltage systems. Waterproof and dustproof power and lighting distribution box. The electrical components selected for the distribution box are advanced. Its main electrical properties, such as breaking capacity, thermal stability and insulation properties, can meet higher requirements to meet the needs of different users in industrial and civil buildings. The trial production success and promotion of this product will completely replace the "XL-21" type and similar power distribution box, which has been welcomed by users in the application.

 

Characteristics

◆ Integrates energy metering, power, lighting distribution, reactive power compensation and electric shock protection.

◆It has the advantages of small size, easy installation, lightning protection, low cost, strong adaptability and accurate compensation.

◆It is easy to move as a whole. It can be installed indoors or outdoors near the distribution transformer. It can also be integrated into the distribution transformer to integrate it, which can effectively prevent electricity theft.

◆Reliable operation and high protection level are ideal products for rural power grid reconstruction.

◆ There are a variety of box types and specifications for users to choose, and can be customized according to user requirements.
