Our Custom 3-Phase Low Voltage Distribution Box is a versatile power management solution designed for demanding commercial and light industrial environments. By combining a rugged powder-coated steel chassis with a high-impact ABS plastic door and cover, this unit offers superior mechanical protection without compromising on aesthetic appeal or weight.
This distribution box comes standard with a high-performance 63A Main Circuit Breaker, providing immediate overcurrent and short-circuit protection for your 3-phase power system. Whether you are outfitting a new workshop, a commercial kitchen, or an office floor, this load center provides a safe, organized, and durable hub for all your branch circuits.
Hybrid Material Durability: The steel base provides rigid structural integrity for heavy cabling, while the ABS cover offers excellent electrical insulation and resistance to chemical corrosion and impacts.
Pre-Wired 63A Protection: Save on installation time and costs with a pre-installed 63A main isolator, rated for 3-phase 380V–415V operation.
Modular DIN-Rail Design: Features an adjustable internal 35mm DIN-rail, allowing for the flexible addition of MCBs, RCBOs, or surge protectors (SPD) from any major global brand.
Superior Safety Sealing: Engineered with a dust-proof seal and a lockable transparent door, allowing for quick status monitoring while preventing unauthorized access to live components.
Ample Wiring Space: Designed with a spacious interior to accommodate large-gauge cables, ensuring proper bending radii and reducing heat buildup within the cabinet.

Industrial Workshops: Centralized power distribution for small machinery, 3-phase compressors, and power tools.
Commercial Kitchens: Managing high-load appliances like industrial ovens, refrigerators, and dishwashers.
EV Charging Stations: Providing a localized and protected power source for 3-phase electric vehicle chargers.
Office Buildings: Reliable floor-level distribution for HVAC units, server racks, and lighting circuits.
Total Customization: We offer tailored configurations for cable entry points (knockouts) and can provide the unit "empty" or fully populated with your choice of branch breakers.
Installer-Centric Design: Features removable top and bottom plates for easy conduit entry and a reversible door that can be adjusted for left or right-hand opening.
Anti-Corrosive Finish: The steel components undergo a multi-stage pickling and phosphating process followed by epoxy powder coating to ensure no rust, even in humid environments.
Thermal Efficiency: The hybrid material choice helps dissipate heat faster than fully plastic enclosures, increasing the lifespan of the internal electronics.
Q: Can I upgrade the main breaker to a higher amperage later?
A: Yes. The internal busbar and DIN-rail are designed to accommodate breakers up to 100A, though the standard 63A is ideal for most commercial branch applications.
Q: Is the ABS material flame retardant?
A: Absolutely. We use high-quality, UL-rated flame-retardant ABS that is self-extinguishing to ensure the highest safety standards in the event of an electrical fault.
Q: Does it come with grounding and neutral bars?
A: Yes, every unit includes high-conductivity brass neutral and earth terminal blocks pre-mounted for fast and safe wiring.

Low voltage power distribution cabinet
|
||||
|
XL-21 Low-voltage power distribution cabinet is suitable for power distribution of three-phase four-wire or three-phase five-wire system with AC voltage of 500 volts and below in power plants and industrial and mining enterprises. XL-21 low-voltage power distribution cabinet is installed against the wall of the indoor device, and inspected in front of the screen. The shell IS made of steel plate bending, and the knife switch handle is on the upper part of the right column in front of the box, which can be used for switching power supply. According to the needs of users, different types of circuit breakers with different current levels can be selected to meet the needs of different users.
