Low Voltage Switchgear

This low-voltage electrical distribution cabinet is designed for AC380V/50Hz 3-phase 3-wire, 4-wire, or 5-wire power distribution systems. It supports a rated current of up to 630A and integrates circuit monitoring, equipment start/stop control, and comprehensive protection against overload, short-circuits, and earth leakage. The enclosure is constructed from 1.2mm cold-rolled steel and utilizes high-purity TMY copper busbars (compliant with national standards). It features a standard IP30 protection rating (upgradable to IP54) and supports both standalone and side-by-side modular installation; internal components can be supplied as standard national-compliant parts or customized to specific requirements.

The MNS low voltage switchgear serves as core equipment in power distribution systems for industrial plants, petrochemical bases, power stations, and high-rise buildings. HUAJIDIAN products feature a fully modular, standardized structure, supporting a maximum main busbar current of 6300A and a short-time withstand current of 100kA. They come equipped with smart communication interfaces and an IP41 protection rating, holding full ISO9001 and CE certifications. Backed by rigorous quality control within our own standardized manufacturing facilities, this equipment has been successfully deployed in numerous large-scale domestic projects.

As a professional Chinese manufacturer of low-voltage power distribution equipment, HUAJIDIAN independently develops and produces the GCS low voltage switchgear. Designed for modern industrial and civil power distribution systems, this product utilizes a mature, modular, withdrawable-drawer structure, offering easy maintenance, high safety, strong compatibility, and stable operation. The equipment strictly adheres to national and industry standards, supports automated networked control, and is widely suitable for complex distribution scenarios such as power plants, petrochemical facilities, industrial manufacturing sites, and high-rise buildings.

With over a decade of expertise in low-voltage power distribution, HUAJIDIAN specializes in GCK low voltage switchgear rated for AC 400V/50Hz and currents of 400–3150A. Featuring three-position mechanical interlocking drawer units, this equipment offers high short-time withstand current capabilities and flexible protection ratings. It supports intelligent monitoring, customized anti-corrosion/moisture-proof treatments, and pre-installation site surveys, making it widely used in domestic industrial, commercial, and rail transit projects.

HUAJIDIAN is a China-based manufacturer specializing in electrical equipment, with decades of expertise in the R&D and production of GGD low voltage switchgear. This stationary low-voltage power distribution equipment complies with GB7251.1 and IEC60439 standards. With a rated operating current range of 630A to 3150A, it facilitates power conversion, distribution, load protection, and equipment start/stop control for power plants, industrial and mining facilities, chemical parks, and commercial or residential projects.
