Understand the difference between distribution cabinets and distribution boxes at 5 o'clock
2017-02-06
Distribution cabinets contain a large amount of parameter data and generally constitute low-voltage electrical wiring. Based on the electrical wiring, switchgear, measuring instruments, protective devices, and auxiliary equipment are assembled in enclosed or semi-enclosed metal cabinets or panels, forming a low-voltage distribution box. Distribution boxes are characterized by their small size, easy installation, good technical performance, fixed position, good configuration functions, unrestricted location, stable and reliable operation, high space utilization rate, small footprint, and good ecological environmental protection effects. Below, we will explore the differences between distribution boxes and distribution cabinets from five aspects.
From a usage perspective: distribution boxes are generally used for household purposes, while power distribution cabinets are mostly used for centralized power supply, such as industrial and building power supply. Both distribution boxes and power distribution cabinets are complete sets of equipment; distribution boxes are low-voltage complete sets of equipment.
The basic difference in appearance and size lies in their size. Distribution cabinets are placed on the ground and are about the size of a refrigerator. Distribution boxes are as small as a box fixed to a wall; both have the same function.
Distribution boxes are generally suitable for end-product lines, and can be operated by non-professionals; the large current is 250A. Distribution cabinets are generally used for the control and distribution of electrical energy and have different applicable standards.
From a formal perspective, distribution cabinets, as the name suggests, are vertical cabinets, while distribution boxes are box-shaped.
Functionally, distribution cabinets can be equipped with various explosion-proof electrical appliances or combinations of explosion-proof electrical appliances, such as: explosion-proof power supplies, lighting, distribution boxes, explosion-proof electromagnetic starters, explosion-proof power supply inspection boxes, etc. Distribution boxes can be equipped with circuit breakers, contactors, thermal relays, buttons, and indicator lights, and can be used for lighting and motor control.
