Electrical MCB Distribution Box 220V 380V 690V Multi Voltage Circuit Breaker Cabinet

Our Multi-Voltage MCB Distribution Cabinet is a heavy-duty electrical solution designed to provide centralized protection and distribution for complex industrial grids. Uniquely engineered to operate across a wide voltage spectrum—from standard 220V/380V up to high-demand 690V industrial systems—this cabinet is the primary choice for factories, mining operations, and heavy infrastructure projects.

Built with a high-strength metal chassis and equipped with standard 35mm DIN-rails, this power cabinet accommodates a variety of Miniature Circuit Breakers (MCB) and Moulded Case Circuit Breakers (MCCB). It serves as a reliable firewall for your electrical system, protecting downstream equipment from overloads, short circuits, and phase imbalances.

• Wide Voltage Range Capability: Rated for 220V, 380V, 415V, and 690V applications, offering a universal solution for diverse regional power standards and heavy-machinery requirements.

• Reinforced Steel Construction: Manufactured from 1.5mm–2.0mm thick cold-rolled steel with a high-durability epoxy finish to withstand the mechanical stresses of industrial environments.

• Modular DIN-Rail Flexibility: The internal layout supports high-density MCB installation, allowing for the organized management of up to 48+ branch circuits in a single enclosure.

• Superior Ingress Protection: Available in IP54 or IP65 configurations, featuring a full-perimeter polyurethane gasket to seal out dust, metallic filings, and moisture.

• High-Conductivity Busbar System: Features tinned copper busbars designed to handle high current loads with minimal thermal rise, even at 690V operation.

1. Mining & Heavy Industry: Providing localized 690V power distribution for heavy-duty motors and extraction equipment.

2. Commercial Real Estate: Centralized 220V/380V distribution for lighting, HVAC, and power outlets in office towers.

3. Industrial Automation: Housing PLC controls and MCB branch protection for assembly line robotics.

4. Oil & Gas Facilities: Rugged power cabinets for remote monitoring and pump control stations where high insulation voltage is required.

• Anti-Condensation Design: Specifically engineered for outdoor or humid indoor use, with optional thermal management systems to prevent moisture buildup at high voltages.

• Custom Knockout Options: We provide precision CNC-cut entry points tailored to your conduit requirements, ensuring a clean, airtight installation.

• Enhanced Safety Isolation: Features internal transparent shields (dead-fronts) that allow operators to inspect breaker status without exposure to live 690V busbars.

• Rapid Maintenance Access: The wide-opening door (up to 130°) and depth-adjustable DIN-rails allow technicians to replace breakers or pull new cables with minimal downtime.

Q: Is a 690V rating necessary for standard factory use?

A: While standard factories use 380V/415V, the 690V rating indicates a higher insulation quality (Ui 1000V). This provides a significant safety margin and longer service life for the cabinet, even when operating at lower voltages.

Q: Can this box be pole-mounted for outdoor use?

A: Yes. We offer specialized pole-mounting bracket kits and a top-mounted rain hood to ensure the unit remains secure and dry in outdoor utility applications.

Q: Do you supply the unit with pre-installed breakers?

A: We can supply the "empty" enclosure for local assembly or a "fully-wired" power cabinet populated with high-end breakers (Schneider, ABB, or Siemens) based on your circuit schedule.

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.
