Operating mechanism

The operating mechanism is, besides the interrupter, the most important component of the breaker. HMB and HMC allow for simple and easy adaptation to all circuit-breaker types, thus covering a wide range of applications.

It is a mechanism that processes synchronization and communicates with each other. But, using this mechanism, the processes can communicate without the shared variables being restored. Generally, the inter-process communication mechanism provides two operations that are as follows: send (message) received (message)The operating mechanism provides a means of opening and closing the toggle mechanism of quick-make/quick-break type contacts (snap open or closed independent of the speed of handle movement). NOTE // The breaker is trip free and cannot be prevented from tripping by holding the breaker handle in the “on” position during a fault condition.The mechanism is overseen by the CDM Executive Board, answerable ultimately to the countries that have ratified the Kyoto Protocol.
