Low Voltage Distribution Box

The low voltage distribution box is purpose-built for the toughest environments on a vessel-the engine room. Engine rooms are hot, humid, and filled with vibration. Ordinary distribution boxes fail here. Ours don't.

Designed specifically for marine power systems up to 1000V AC and 500V DC, this low voltage distribution box distributes electrical power from the main switchboard to branch circuits throughout the engine room, powering everything from pumps and compressors to ventilation fans and control systems. The enclosure is constructed from high-quality cold-rolled steel plate with surface spray treatment, providing excellent resistance to corrosion, moisture, and mechanical stress.

We've supplied these low voltage distribution box units to shipyards and vessel operators across Asia, Europe, and the Middle East. One of our clients-a major shipbuilder in Southeast Asia-recently outfitted four newbuild cargo vessels with our low voltage distribution boxes. They came back for the next project. Why? Because reliability at sea isn't optional.

- Cold-rolled steel enclosure with anti-corrosion surface treatment
- Overload, short-circuit, and leakage protection functions
- Multiple branch circuits for zoned power distribution
- Wall-mounted or floor-standing installation options
- Protection level IP56 / IP66 for harsh marine environments
- Operating temperature range: -25°C to +55°C

This low voltage distribution box is essential for:
- Marine engine room power distribution
- Shipboard lighting and power systems
- Offshore platforms and installations
- Vessel auxiliary machinery power supply

We've been manufacturing electrical equipment for over 20 years. Our 12,000-square-meter facility in Jiangsu Province houses 5 automated production lines and employs 75 people-46% of whom are technical professionals. Our annual production capacity exceeds 10,000 units. We hold ISO9001, ISO14001, ISO45001, CQC, and CCC certifications. Every low voltage distribution box is built to marine-grade standards and undergoes 100% inspection before leaving our facility.

Need a low voltage distribution box with specific circuit configurations? We support OEM/ODM services and can manufacture based on your technical drawings or prototypes. Our engineering team works with you to design the optimal solution-whether you need different enclosure sizes, specific brand components (Schneider, Siemens, Chint, Delixi), or custom protection schemes. MOQ is flexible. Custom sample development typically takes one week. We offer a 2-year warranty on all products.

Quality control on every low voltage distribution box starts with material selection-we use only premium cold-rolled steel and brand-name electrical components from Schneider Electric, Siemens, Chint, and Delixi. Throughout production, we conduct multiple inspection points: raw material verification, in-process checks, electrical testing (including power-on and partial discharge tests), and final 100% inspection before packaging. We accept third-party inspections and welcome client visits to our facility for pre-shipment verification.
