The Tavrida Electric indoor switching module has a simplified mechanical structure. It uses three single-coil magnetic
actuators, one per pole. All switching elements are assembled along a single axis. All mechanical operations, are
therefore, direct and linear. Three actuators are installed in a steel frame and mechanically linked by a synchronizing
plate.
This design eliminates failure modes caused by components in conventional technology such as gears, charging
motors, and trip/closing coils.
Tavrida Electric manufactures vacuum interrupters which combine small dimensions with an extraordinarily long
mechanical and electrical lifespan. The use of a specially designed axial magnetic field distribution provides even current
density distribution over the contact surface, and consequently a substantial improvement in vacuum interrupting
performance.
The result is up to 30,000 CO cycles at rated current or up to 50 operations at maximum short-circuit breaking current
without replacing or adjusting any parts of the circuit breaker. Tavrida Electric vacuum circuit breakers are completely
maintenance-free over a total life expectancy of at least 30 years.
The ISM15_LD_8, ISM15_MD_1, ISM15_HD_1 and the ISM25_Shell_2 possess the following parts: an interface for
auxiliary circuits, a main contacts position indication and an interlocks connection.
