The FLa 15/97 are very reliable, high quality air-insulated pole mounted load break switches with vacuum interrupters to extinguish the arc. They are available with rated voltages from 12 to 38.5kV and rated currents 400 or 630A suitable for horizontal or vertical installation.

The vacuum interrupter is embedded in a patented weather-proof polymeric housing providing the external insulation strength without the need of a liquid or gaseous medium. This switchgear is therefore also recommended for special applications e.g. in water protection areas.

The FLa 15/97 is capable of switching its rated current as well as its rated short-circuit making current via the main contact system. The disconnection via the shunt-connected vacuum interrupters results in no external arcing phenomena.

The FLa 15/97 are tested according to latest standards and designed for use under normal operating conditions.
