vacuum circuit-breakers may be provided with auxiliary switches, auxiliary current releases, indirect overcurrent releases and under-voltage releases. The vacuum circuit-breakers are fitted with an energy-storing drive for manual or electrical tensioning and optionally for fast auto-reclosure.
The force required for making and breaking is transmitted between energy storing device and switch poles by means of a hook stick made from high-quality glass-fibre reinforced insulating material, which is substantially unloaded when the vacuum circuit-breaker is made.
