Power distribution cabinet (box) sub-power distribution cabinet (box) and lighting distribution cabinet (box), measuring cabinet (box), is the final power distribution system equipment. Distribution cabinet is the motor control center collectively. Distribution cabinet used in the load is more dispersed, less circuit occasions; motor control center for the load concentration, the circuit more occasions. They allocate the power of a circuit of a power distribution equipment to a nearby load. This level of equipment should provide protection, monitoring and control of the load.

    Power cabinet is to the whole machine to provide the power of the normal operation of the electrical control cabinet combination, with contactors, frequency converters, high voltage cabinets, transformers, etc.

Power cabinet role:

1, to the power supply equipment (to provide power to the device);

2, start and stop operation of electrical equipment (with start and stop button);

3, the detection equipment operation (set the signal indicator, there ammeter voltmeter);

4, protection of electrical equipment (circuit breakers) power cabinet is the distribution cabinet, is dedicated to the power equipment (usually refers to the motor) to provide power and control of the distribution cabinet.

10kv high voltage cabinet and 400v low voltage cabinet (regardless of line, outlet, measurement, capacitance, contact, pressure change, etc.) can be called the distribution cabinet.

400v low voltage cabinet the following equipment, the secondary side of the outlet load for the power facilities (such as fans, motors, pumps, etc.), then called the power cabinet. The load for the lamps, switches, sockets such equipment is called distribution box.

       Distribution box: a small power distribution box, which contains the power switch and safety devices.

       Control box: A small control distribution box with internal power switch / safety device / relay (or contactor) that can be used for specified equipment control, such as motor control.

       Distribution cabinet: the actual distribution box is large, can provide greater power or more channel power output.

       Control cabinet: the actual control box is large, can provide a larger power or more channel control output, you can also achieve more complex control.

       Control panel: only the front of the control cabinet, all the internal equipment installed on the panel.
