Product Features

1. lt can be increased the thermal capacity of adaptor parts. Also it can beeffectively and evidently reduced the temperature rise of adaptor parts or additional temperature rise of cable lug and partition board.
2. The quantity of a single MCC panel’ s loop is up to 22 Nos., this can satisfyrequirements of power plant which has high capacity of single generator automatic motor control door (machine) set of petrochemical system an
3. The connection between the device and the external cable is completed inthe cable compartment, and the cable can get in and out on the top or  The zero sequence current transformer is placed in the cable compartment, so that the installation and maintenance are convenient.
4. Drawer units have enough quantity secondary adaptors (32 pairs for 1 unitand above, 20 pairs for 1/2 unit), so it can meet the requirements of the number of contacts by the computer interface and the automatic control
