Our medium voltage indoor air insulated load break switches
are very reliable switching devices which have been
used hundred thousand fold successfully many years
in various medium voltage switchgears. The devices
are fitted with an energy storage mechanism for quick
operation.
Due to very high operating frequencies and a minimum
amount of maintance required they provide the daily
loads exerted under normal switching duty
- for interrupting ring feeders
- disconnecting and protecting distribution transformer
- etc.
The load break switches are designed for normal operating
conditions according to DIN VDE 0670 and IEC 60697,
class
„Minus 5 Indoor“ and are type tested according
to IEC60265-1.
