XL-21 Low-Voltage Power Distribution Cabinet Series
The XL-21 low-voltage power distribution cabinet is suitable for use in power plants and industrial/mining enterprises, serving as a power distribution unit in three-phase four-wire systems with AC voltages of 500V or lower.
The XL-21 low-voltage power distribution cabinet is designed for indoor installation, mounted against a wall, with maintenance accessible from the front of the panel.
Structural Features
The XL-21 low-voltage power distribution cabinet is a closed-type design, with a housing fabricated from pressed steel plates. The knife switch operating handle is mounted on the upper part of the front-right post, enabling easy switching of power sources. A voltmeter is installed on the front panel to indicate the busbar voltage. The cabinet features a hinged door; when opened, all internal components are fully exposed, making maintenance and repairs straightforward. This distribution box incorporates domestically designed modular components, offering advantages such as a compact structure, convenient access for servicing, and flexible configuration options for wiring schemes. In addition to air circuit breakers and fuses for short-circuit protection, the cabinet is equipped with contactors and thermal relays. An optional feature includes mounting operation buttons and indicator lights directly on the front door.
