Lighting Distribution Box

1. The lighting distribution box equipment is a device responsible for completing power control, protection, conversion, and distribution at the end of the low-voltage power supply system. The lighting distribution box integrates functions such as power distribution, control, protection, and intelligent management. In terms of power distribution, it can reasonably distribute the upper-level power supply to multiple lighting circuits to meet the electricity needs of lamps in different areas and types.

2. By configuring components such as miniature circuit breakers and residual current protectors, it realizes overload, short-circuit, and leakage protection for the circuit. When an abnormality occurs in the circuit, it quickly cuts off the power supply to avoid accidents such as electrical fires.

3. In addition, the lighting distribution box can also be equipped with a surge protector according to requirements to prevent damage to lamps and lines caused by lightning strikes, power grid fluctuations, etc., and ensure the stable operation of the lighting system.

1. The product uses high-quality raw materials, and the main body of the lighting distribution box is made of high-strength cold-rolled steel plate or high-quality engineering plastics. The high-strength cold-rolled steel plate undergoes CNC stamping, bending and welding processes to form a sturdy and durable box structure that can withstand external force impacts during transportation and installation, and the box molding error is controlled within ±0.5mm.

2. The surface of the lighting distribution box is treated with multiple layers of anti-corrosion treatment such as pickling, phosphating, and electrostatic powder spraying to effectively resist erosion by environmental factors such as moisture and dust, and extend its service life.

3. The conventional thickness of our distribution box is 2.0mm, but the thickness can be customized according to user requirements.

4. The appearance design of the lighting distribution box is simple and generous, with smooth lines. The surface is treated with matte frosted texture, which is anti-fingerprint and scratch-resistant, and can be perfectly integrated with various architectural decoration styles.

5. The box door adopts a large-angle opening design, the internal components are reasonably arranged, and the terminal markings are clear, which is convenient for construction personnel to install, debug and repair.

6. We have established a complete after-sales service system to provide professional technical consultation, installation guidance and fault repair services.

1. The lighting distribution box adopts enhanced hinges and door locks. The hinge bearing capacity reaches 30kg, and the number of switching times exceeds 100,000; the door lock has anti-prying and anti-collision functions to ensure that the box is not easy to be damaged after long-term use.

2. Our lighting distribution box is reasonably designed with a compact box structure, occupying small space, and supports wall-mounted or embedded installation, which is suitable for different installation environments.

3. The interior of the lighting distribution box also reserves sufficient wiring space and spare terminals, which is convenient for later line expansion and transformation; it is equipped with a dedicated ground bar and neutral bar, and the grounding resistance is less than 0.1Ω to ensure the reliability of the grounding system.

4. Key parts such as incoming and outgoing wire holes are equipped with rubber sealing sleeves to prevent dust and moisture from entering the box.

5. Customizable: The box has a variety of size specifications to meet different installation space requirements. The product supports customization, and we can carry out personalized design and production according to your needs.

• Temperature range: conventional model: -15℃～+60℃ (no condensation).

Note: When the temperature exceeds 40℃, it is necessary to derate or strengthen heat dissipation measures.

• Humidity requirements: indoor type: relative humidity ≤90% (at 25℃), no condensation.

Outdoor type: can withstand short-term rain, and need to be equipped with a moisture-proof heating module for long-term environment with humidity >95%.

• Altitude: standard design: ≤2500 meters.

High-altitude customization: When the altitude is >2000 meters, it is necessary to improve the insulation level and use it with derating (for every 1000 meters increase in altitude, the rated current is derated by 10%).

• Protection level adaptation:

IP30: dry and clean indoor environments (such as offices, shopping malls).

IP65: outdoor, underground garages, humid workshops and other scenes that require dust and water resistance.

Explosion-proof type (Ex d IIB T4): flammable and explosive places such as chemical industry and oil and gas stations.

• Installation location:

Keep away from heat sources (such as boilers, radiators), vibration sources (such as large motors) and corrosive gases.

Install vertically with an inclination ≤5° to ensure unobstructed heat dissipation air ducts.

Reserve ≥0.8 meters of operating space in front of the box for easy maintenance.

If you have special requirements, you can negotiate with us, and we can customize according to your special environmental requirements.

Q: How to choose between single-phase electricity and three-phase electricity?

A: Single-phase distribution boxes (220V) are suitable for small buildings or home lighting; three-phase distribution boxes (380V) are suitable for high-power, multi-circuit scenarios such as industrial plants and commercial complexes, which can balance three-phase loads and improve efficiency.

Q: Is it necessary to equip a residual current protector in the lighting distribution box?

A: In humid environments (such as bathrooms, outdoors) or crowded places (schools, hospitals), a 30mA residual current protector must be configured; it can be optionally configured according to needs in ordinary dry areas.

Q: What are the requirements for the installation location of the lighting distribution box?

A: Avoid high temperature, flammable materials or under water pipes.

Keep ≥30cm space around the box to ensure heat dissipation and operation safety.

A rain cover must be added or an IP65 box must be selected for outdoor installation.

Q: What does the daily maintenance of the lighting distribution box need to do?

A: Check whether the terminals are loose every six months.

Remove dust inside the box (operate with power off).

Test the leakage protection function (press the test button once a month).

Q: Which distribution box is suitable for industrial plants?

A: The distribution box suitable for industrial plants must meet: high protection level (IP65) + anti-corrosion materials (such as stainless steel).

Multi-circuit design (adapt to high-bay lights, emergency lighting).

Reserve 10%~20% spare circuits.

Q: How to get a quotation for the lighting distribution box, and what do I need to provide?

A: If you need a quotation for the lighting distribution box, please tell us your requirements, such as: rated voltage, rated current, number of poles, box size, protection level, purchase quantity, delivery cycle, logistics and packaging, etc. We will quote according to your needs.

We have established a complete quality inspection system. Before the lighting distribution box leaves the factory, we will conduct product tests on the product, such as electrical performance test, box protection level (IP code) test, ground continuity test, temperature rise test, environmental adaptability test, vibration and impact test, etc. Only products that pass all testing items can be affixed with a qualified label and enter the finished product warehouse.
