Specifically, the track is formed by a stainless steel sheet through sheet metal machining, the middle of the track is attached to a rear side plate of the box body, screw holes are formed in the middle of the track and in positions corresponding to the rear side plate of the box body and fixedly connected through bolts, edges of the upper side and the lower side of the track are bent towards the inside of the box body, and the length of the track is slightly smaller than that of the rear side plate of the box body; the slider is also formed by a stainless steel sheet through sheet metal machining, the vertical section of the slider is a rectangle with a notch at the rear side, the slider is held outside the edges of the two lower sides of the rail, and the front side of the slider is provided with a screw hole and is fixedly connected with the circuit breaker through a bolt.

Furthermore, 22 circuit breakers are mounted on the track at most, 22 rectangular knockout holes are formed in the front side of each circuit breaker, the circuit breakers and the rectangular knockout holes can correspond to one another, and the utility of the PDM power distribution unit is maximized.

The junction of the left side plate and the right side plate of the box body and the front side plate of the box body extends outwards, the extending part and the front side plate of the box body are located on the same plane, and the extending part is provided with a plurality of waist holes to adapt to connection and fixation of cabinets of different specifications.

When the power distribution unit is used, the PDM power distribution unit is fixed in a cabinet by using spring screws or waist holes, the position and the number of short-circuit devices on a track are adjusted as required, and rectangular blocks in the holes are lightly knocked off by using a starter or other tools on a box body top plate at the front side of the position corresponding to the breaker. The mounting hole is used for installing the slider and the circuit breaker, also can be used for walking the line, and the anti-cutting strip covers the mounting hole edge and is convenient for install and walk the line safety.

The PDM power distribution unit can flexibly knock down the rectangular plate in the knock-down hole at the position required to be installed when a small number of circuit breakers are used, is attractive and elegant, and meets the installation requirement of a standard cabinet. Compared with the traditional PDM power distribution unit, the PDM power distribution unit can meet the requirement of PDM installation of the machine room flexibly, and is more flexible, durable and efficient.
