63A Current Metal Steel MCB Power Electric Distribution Cabinet Low Voltage

Product Overview

The 63A Low Voltage Metal Steel Distribution Cabinet is a high-durability power management solution engineered for environments where plastic enclosures simply won't suffice. Constructed from heavy-gauge cold-rolled steel, this cabinet is designed to provide a secure, fireproof, and impact-resistant housing for miniature circuit breakers (MCBs) and other DIN-rail components.

Equipped with a pre-integrated 63A Main Switch, this power cabinet is optimized for 3-phase and single-phase electrical distribution in industrial workshops, warehouses, and commercial infrastructures. Its rugged "Metal-Clad" design ensures maximum protection against mechanical damage and environmental dust, making it the gold standard for reliable power delivery.

Key Technical Advantages

• Heavy-Duty Steel Shell: Manufactured from 1.2mm–1.5mm high-grade steel with a multi-stage pickling and phosphating process to prevent rust and corrosion.

• Pre-Installed 63A Protection: Features a high-performance 63A main breaker, ensuring immediate overcurrent and short-circuit protection for downstream branch circuits.

• Fire-Resistant & Secure: Unlike ABS boxes, the steel construction provides superior fire containment and is equipped with a lockable door to prevent unauthorized tampering.

• Universal 35mm DIN-Rail: Includes an adjustable internal mounting rail, allowing for the seamless integration of MCBs, RCBOs, contactors, and surge arrestors (SPD) from all major global brands.

• Industrial Epoxy Finish: Coated with a UV-stabilized epoxy powder finish (Standard RAL 7035), providing a professional appearance that resists scratching and chemical exposure.

Technical Specifications

Primary Application Scenarios

1. Industrial Workshops: Centralized power distribution for 3-phase machinery, compressors, and high-load power tools.

2. Commercial Warehouses: Managing high-bay LED lighting, loading dock motors, and office power circuits.

3. Construction Sites: Rugged, temporary power boards that can withstand the physical rigors of a job site.

4. Data & Telecom Rooms: Providing localized, fireproof circuit protection for server racks and UPS systems.

Why Specify Our Steel Distribution Cabinets?

• Fully Customizable Knockouts: We provide pre-stamped or CNC-customized cable entry points on the top and bottom to accommodate various conduit sizes for a clean, professional finish.

• Spacious Interior: The "Spacious-Wiring" design allows for generous cable bending radii, which reduces heat buildup and simplifies the installation of large-gauge feeder wires.

• Total Electrical Continuity: Features dedicated copper-plated grounding studs on both the cabinet body and the door, ensuring full compliance with international safety grounding standards.

• Reversible Door Design: The heavy-duty door can be adjusted for left or right-hand opening, providing flexibility in tight electrical closets.

FAQ

Q: Can this steel box be used outdoors?

A: The standard model is IP40/IP41 for indoor use. However, we offer an Outdoor Weatherproof Version featuring a sloped rain hood and a full-perimeter polyurethane gasket to achieve an IP55/IP66 rating.

Q: What is the benefit of a steel box over a plastic one?

A: Steel offers superior impact resistance, better heat dissipation for high-current breakers, and is non-combustible, making it mandatory in many commercial building codes.

Q: Does it include the internal wiring?

A: We supply the cabinet with pre-installed busbars and terminal blocks. We can also provide a "fully-wired" solution with branch MCBs pre-installed based on your specific circuit schedule.

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.
