Features

Using high-quality steel as the material, electroplating and spraying plastic, the appearance is beautiful, the structure is firm;

Double-sided cabinet, using LXAS porous column, optimized by ABB, Siemens and LX structure, easy to operate and maintain;

Regardless of the structure size and appearance color, Jun can match the communication equipment used in China.

The AC power distribution method adopts secondary distribution. For a rack of 2200 (height) × 1200 (width) × 600 (depth) mm, the detection module unit of the equipment under the cabinet can be used for the main and standby fuses and the main Use 24 channels and 24 spare channels of shunt fuses (or circuit breakers) for a total of 48 channels for single-phase 220V AC power distribution (three-phase if required by the user), and monitor the frame size, number of phase lines, number of branches, Corresponding fuse current, etc., can be increased or decreased according to user needs (see the schematic diagram of the secondary distribution of the power supply).

The main fuse of the phase line can be a three-phase plastic case circuit breaker (see Figure 1); the shunt fuse of each phase line can be a self-restoring satellite circuit breaker, regardless of the corresponding each of the main fuse and the shunt fuse. Each phase line is equipped with a current transformer (see Figures 1 and 2) to make the equipment reliable and easy to operate.
The monitoring unit is shown in Figure 3.

The cabinet has a good grounding system.
