Do You Know The Little Knowledge Of Power Distribution Cabinets And Distribution Boxes

1. In terms of usage, power distribution boxes are generally used for household use, while power distribution cabinets are mostly used in centralized power supply, such as industrial power and building power, etc., power distribution boxes and power distribution cabinets are complete sets of equipment. The distribution box is a low-voltage complete set of equipment, and the distribution cabinet has high voltage and low voltage.

2. From the appearance size, the most basic difference lies in the size. The power distribution cabinet is placed on the ground and is as big as a refrigerator. The distribution box is as small as a box set on the wall, and the two functions are the same.

3. The distribution box is generally applicable to the standard GB7251.3 for terminal products and can be operated by non-professionals, with a maximum current of 250A. The power distribution cabinet is generally used for controlling and distributing electric energy with different applicable standards.

4. In terms of form, the power distribution cabinet is a vertical cabinet as its name suggests, while the distribution box is a box type.

5. Functionally, the power distribution cabinet can be equipped with various explosion-proof electrical appliances or various combinations of explosion-proof electrical appliances, such as: explosion-proof power (lighting) distribution box, explosion-proof electromagnetic starter, explosion-proof power maintenance box, etc.; and the power distribution box can be equipped with a circuit breaker. Components such as sensors, contactors, thermal relays, buttons and indicators can be used for lighting and power motor control purposes.

There are two types of distribution box structures

1. Welding structure: simply cut, bend, open holes and then weld the sheet metal parts.

2. Assembling structure: the sheet metal parts are processed separately. After each part is processed, it is assembled and locked with screws and three links. The appearance is beautiful and the operation is simple, which can save a lot of transportation costs.

Distribution boxes and power distribution cabinets, power distribution boards, power distribution panels, electrical cabinets, etc., are complete sets of equipment for centralized installation of switches, meters and other equipment.

The power distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box). It is the final equipment of the power distribution system. The power distribution cabinet is the general term for the motor control center. 

The power distribution cabinet is used in the occasions where the load is relatively dispersed and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby load. This level of equipment should provide protection, monitoring and control of the load.
