Mobile Temporary Three-Phase Power Distribution Box

Shangming is a professional manufacturer and supplier of Mobile Temporary Three-Phase Power Distribution Boxes, and we have our own factory. This product is suitable for short-term, variable, and high-load power consumption scenarios; it can be used immediately upon placement without installation.

Product Design

Mobility: The mobile temporary three-phase distribution box features a thickened handle on top and heavy-duty casters or a skid base on the bottom. Its weight and size are optimized for easy movement on the construction site.

Three-phase Input: Utilizes a 5-pin high-current industrial plug or terminal block input to ensure balanced energy distribution.

Extremely High Protection Rating: Considering temporary outdoor power needs, the protection rating can be customized; common options include IP44, IP55, and IP66.

Main Functions

The primary function of the mobile temporary three-phase power distribution box is not only temporary three-phase power distribution, but also crucial for construction sites, temporary events, and emergency power supply. Choosing Shangming's product is also for safety protection, as well as quick use and maintenance.

1. Three-phase Power Distribution

The distribution box supports three-phase power input, capable of simultaneously powering multiple high-power devices. Its diverse output circuits allow for flexible allocation according to construction or temporary power needs.

Our efficient design ensures stable voltage in each circuit, meeting the requirements for safe equipment operation.

2. Electrical Protection and Safety Management

The equipment incorporates circuit breakers, overload protectors, and leakage protection devices to prevent damage to equipment and personnel from short circuits, overloads, or leakage.

Clear circuit markings facilitate quick identification and control by operators.

3. Mobile Deployment

Due to its mobile design, the distribution box is equipped with casters, handles, or lifting rings, allowing for rapid movement to construction sites, event locations, or temporary locations without fixed installation, supporting multi-point temporary power supply.

Considering its frequent use in complex indoor and outdoor environments, the product can withstand construction site dust, slight moisture, and vibration without affecting performance.

4. Cable Connection and Circuit Management

Our product provides standardized cable interfaces and sockets, supporting quick connection and disconnection. Internal circuit wiring is optimized to prevent cable crossing, compression, or damage.

The cabinet has ample internal space for future expansion or addition of circuits.

5. Easy Operation and Maintenance

The mobile temporary three-phase distribution box features a user-friendly front panel with a logical layout of switches, buttons, and indicator lights. Internal components are easy to inspect and replace, reducing maintenance time.

What Are the Applications of Mobile Temporary Three-Phase Power Distribution Boxes?

1. Construction and Civil Engineering

Core Need: Provide reliable three-phase power to distributed, mobile electrical equipment.

Typical Equipment Power Supply: Welding machines, rebar bending machines, concrete vibrators; tower cranes, construction hoists; temporary lighting towers, water pumps, air compressors.

2. Power and Communication Emergency Repair

Core Need: Quickly restore power to critical facilities and ensure the operation of repair equipment.

Application Scenarios: Emergency power supply to communication base stations after typhoons/floods; temporary load transfer during substation maintenance; on-site power supply for fiber optic cable splicing vehicles and cable fault location devices.

3. Large-scale Exhibitions, Events, and Cultural Activities

Core Need: Mobile temporary three-phase power distribution boxes provide safe and compliant temporary power to high-power stage equipment.

Typical Loads: LED screens, audio amplifiers, follow spots; ice makers and coffee machines in catering areas; security gates, temporary office computers.

4. Agricultural and Forestry Field Operations

Core Need: Driving high-power agricultural machinery in areas without power grid coverage.

Application Scenarios: Orchard/farmland irrigation pumps; wood shredders, straw balers; mobile cold storage facilities; livestock feed processing equipment.

5. New Energy Projects

Core Need: Providing temporary power for on-site commissioning of photovoltaic/wind power systems.

Application Scenarios: Electric wrenches and suction cup lifting tools during photovoltaic module installation; charge and discharge testing equipment during energy storage system commissioning; power supply for lighting and tools inside wind turbine towers.

6. Municipal and Public Utility Maintenance

Core Need: Supporting outdoor operations for roads, waterworks, sanitation, etc.

Application Scenarios: Road milling machines, asphalt heating equipment; temporary power supply for sewage pump station dredging equipment; external power supply for sanitation high-pressure cleaning vehicles.

Not applicable scenarios:

Long-term fixed use (>6 months) → Fixed distribution cabinet recommended;

Explosive environments (e.g., oil depots, explosion-proof areas of chemical plants) → Dedicated Ex-certified equipment required;

Extremely high current requirements (>100A) → Mobile distribution cabinet (non-box type) should be selected.
