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.

Simple design
Absolute operation safety
