XL-20

Product Features

The XL-type distribution box is of a closed design, with its outer casing made of bent steel plates. The operating handle of the knife-fuse combination switch is located on the upper part of the right front column of the box, which can be used for power source switching. A voltmeter is installed on the front of the distribution box to indicate the voltage of the busbar. The front of the distribution box is equipped with a door; when the door is opened, all internal equipment of the box is exposed, facilitating maintenance and service. This distribution box adopts domestically independently designed components, featuring a compact structure, convenient maintenance, and flexible combination of circuit schemes. In addition to air circuit breakers and fuses for short-circuit protection, the distribution box is also equipped with contactors and thermal relays, and operational buttons and indicator lights can be installed on the front door.

1. It is divided into two types: the standard type with a box height of 1600mm or 1700mm, which is installed independently, and can have wire inlet/outlet holes opened at the top as required; the type with a box height of 1800mm is equipped with a top busbar, and the top of the box is fitted with a detachable cover plate to facilitate the installation and disassembly of the busbar.

2. The box body uses section steel as the frame; the door panel, side sealing plates, and rear sealing plate are all detachable. The mounting plate and side beams are adjustable, enabling flexible and convenient installation and maintenance, along with a compact structure and good versatility.

3. Precision-cast adjustable door hinges are adopted, allowing the door to open to an angle of more than 135 degrees.

4. After the components are installed, the mounting brackets inside the box can be adjusted as a whole.

5. Wire inlet/outlet can be installed according to different operating environments, featuring good versatility, and multiple units can be used in combination.
