Power distribution cabinets have two main functions
- Nov 21, 2018 -

The first is to distribute and control the electrical equipment, and the other is to provide power-off protection when the circuit is overloaded, short-circuited and leaked.


Power distribution cabinets are widely used for power distribution control of residential buildings, schools and hospitals due to their good functions. Power distribution cabinets, such as lighting distribution boxes and power distribution boxes, are often seen in factory buildings and workshops. In general, power distribution cabinets are mainly divided into primary, secondary and low-level three-level power distribution equipment.


The distribution box has a complicated structure and a large output circuit capacity. It is the power distribution center of the power supply system and will be installed in the substation to distribute the electric energy to the secondary distribution cabinet. Internal components include: busbars (busbars), circuit breakers, conventional relays, integrated relay protection devices, metering instruments, isolation knives, indicator lights, grounding knives, etc.
