core purpose
The core function of this type of enclosure is to split the power supply and provide power to different devices through industrial waterproof plugs and sockets. At the same time, it is equipped with circuit breakers/leakage protectors to achieve overload, short circuit, and leakage protection. It is a "mobile power station" in industrial scenarios.
Design commonalities
High protection level: mostly IP44/IP54/IP67 or even higher, waterproof and dustproof, able to adapt to complex outdoor, humid, and dusty environments.
Modular structure: The material of the box is mostly engineering plastic (ABS/PC), which is sturdy and resistant to falling; The sockets can be combined as needed and configured flexibly.
Easy to carry/install: Most come with handles, while others come with support feet, allowing for temporary movement and wall mounting.
Clear safety signs: Some boxes are equipped with warning signs such as "Danger of Electricity", and some are also integrated with emergency stop buttons and indicator lights to further enhance operational safety.
Common Categories and Scenarios
Typical Scene of Box Features
Small and portable (such as red/white small boxes) construction site temporary lighting, small equipment power supply, portability priority
Medium sized, multi circuit (such as yellow/white multi socket box) exhibition construction, on-site power distribution, and centralized power supply for multiple devices
Large, with emergency stop/(such as red button box) workshop fixed maintenance, high-power equipment distribution, higher safety protection level
Additional notes
The sockets of this type of box are mostly industrial connectors (commonly known as aviation plugs/industrial plugs). Blue usually represents single-phase 220V, and red represents three-phase 380V. The specifications range from 16A to 63A and can be selected according to the load power.
