Rated voltage 12, 24, 36 and 38.5 kV
Rated current 630 A and 1250 A
Switch-fuse combinations are used for operational medium voltage-side on and off switching of distribution transformers in secondary substations. They additionally have the task of protecting these transformers against the impact of internal and external faults.
These combinations comprise a functional unit of switch disconnectors and back-up fuses.
By means of the fuses the breaking capacity of the combination is extended beyond that of a simple switch disconnector up to the rated short-circuit breaking current.
The high-voltage high breaking capacity fuse, according to statistics of the VDN (German Association of Electricity Network Operators) is rated as reliable transformer protection. The h.v.h.b.c. fuse in combination with a switch disconnector provides a simple solution which is very economical to procure and run.
This provides a clear-cut advantage over a circuit breaker with the associated current transformers and overcurrent time protection.
Besides this, the h.v.h.b.c. fuse has a current limiting effect when short-circuits occur and reliably interrupts the fault current of the first half cycle.
These properties are advantageous for the dimensional design of the network.

DRIESCHER - Outdoor Switch-Disconnector
Type FLa 15/97
• Rated voltage 12 kV, 24 kV, 36 kV and 38.5 kV
• Rated current 400 A and 630 A
• 1-pole and 3-pole design
Contrary to former outdoor load-break switches in which it was common practice for the arc to be extinguished in oil, with the new developed outdoor switch-disconnector FLa 15/97 arc extinction takes place in a vacuum interrupter.
Based on a patented insulating system there is also no liquid or gaseous medium required for the external insulation strength of the vacuum interrupters.
The vacuum quenching device is embedded in a weather-proof insulating housing.
This switchgear is therefore also recommended for special applications (e.g. in water protection areas).
The outdoor switch-disconnector is capable of switching on its rated current as well as its rated short-circuit making current via the main contact system.
The disconnecting process is implemented via the shunt-connected vacuum interrupters, resulting in no external arcing phenomena.
A fully developed eccentric make-and-break mechanism operates the vacuum interrupters and ensures Class M2 with regard to the mechanical strength (corresponds to 5000 mechanical operating cycles).Fefer brochure 766e

Marechal Electric manufactures a comprehensive range of both industrial and hazardous-area electrical connectors from 5 to 700A. However given the pressure on costs faced by industry, we are promoting in particular a new concept for our Decontactor sockets. The decontactor has been traditionally used as a general supply socket outlet in various industries up to 250A.
However the decontactor is also switch-rated and thus safe to make and break on load and provide visible isolation. As such a mechanic can disconnect and isolate a motor in seconds without incurring the costs of an electrician. Downtime is reduced with lower labour costs.
With companies looking for every advantage and a relentless drive to reduce costs the decontactor could be the newest concept to help them in pursuit of operating efficiency. Whether it’s a failed motor holding up production, a conveyor that needs to be re-positioned, a mixing vessel for wash down or a fan requiring maintenance there is a decontactor to suit the job offering IP66/67, no access to live parts and proven electrical performance.
We constantly meet plant engineers steeped in the tradition of hard-wiring who then, when presented with the decontactor concept, immediately grasp what a motor connected with a decontactor means in terms of time-saving, cost-saving and enhanced safety.
