Function of Power Distribution Cabinet

1. Supplying power to electrical equipment (providing power to the equipment);

2. Turning electrical equipment on and off (using a start/stop button);

3. Monitoring equipment operation (equipped with signal indicator lights, an ammeter, and a voltmeter);

4. Protecting electrical equipment (circuit breakers). A powbinet is a type of distribution cabinet specifically designed to provide power and control to power equipment (generally referring to electric motors).

A 10kV high-voltage cabinet and a 400V low-voltage cabinet (regardless of the input and output lines, measurements, capacitors, interconnections, voltage transformers, etc.) can all be called distribution cabinets.

For equipment below the 400V low-voltage cabinet, if the secondary output load is power equipment (such as fans, motors, water pumps, etc.), it is called a power distribution cabinet. If the load is lighting fixtures, switches, sockets, etc., it is called a distribution box.

Power box: A small power distribution box containing power switches and fuses.

Control box: A small control distribution box containing power switches/fuses/relays (or contactors) that can be used to control specific equipment, such as electric motors.

Distribution cabinet: Essentially a larger version of a distribution box, capable of providing higher power or more power output channels.

Control cabinet: Essentially a larger version of a control box, capable of providing higher power or more control output channels, and can also implement more complex controls.

Control panel: A control cabinet with only a front panel; all internal equipment is mounted on the panel.
