General information

Our medium voltage vacuum circuit breakers for indoor
installation TCB series are “sealed for life” pressure
systems (IEC 62271-100 and CEI 71-1 Standards) and
they are constructed using the separate pole technique.
Each pole has a vacuum interrupter inside it which, thanks
to a special production process, is incorporated in the
resin. This construction technique ensures protection of
the vacuum interrupter against impact, dust and
condensation phenomena and guarantees the lightning
impulse withstand also on the external surface of the
vacuum interrupter.
The transmission is obtained by a mechanical central bar
which allows to transform the circuit breaker in different
executions very easily
