The Main Disconnect Switch Has The Following Features:
1. An electrical interval is provided during the inspection of electrical equipment and is a clearly visible disconnect point to safeguard the personal safety of maintenance personnel.
2. The main disconnect switch can not be operated with load: it can not be operated with rated load or large load, and can not divide and combine the load current and short-circuit current, but the arc extinguishing chamber can be operated with small load and no-load line.
