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.

Outdoor Switch-disconnector FLa15/60
used for vertical and horizontal mounting on wooden or concrete pole
Rated voltage 12, 24, 36 and 38.5 kV
Rated current 400 and 630 A
For decades DRIESCHER - Outdoor switch-disconnector have been used as line sectionalizers in medium voltage overhead line networks and have
proven to be extremely satisfactory based on their reliability and operating safety.
The switch is in compliance with the regulations as per DIN VDE 0670
Part 301.
The arc extinguishing device in its weatherproof housing, operates in accordance with the oil flow principle of the well-established DRIESCHER circuit-breakers and is shunted in the On condition.

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

Looking into the future!
Finland, Jyvaskala January 2006 Jean Mueller launched their new IP20 protected L-shaped busbar system for the Scandinavian market. This system was especially designed for the Jean Mueller, vertical SL-fuse switch disconnector cassette system to protect people from touching the live copper bars. Next to their already existing busbar solution with flat copper bars this completes the ranges for the Scandinavian market. The question now rises if there is an enclosure solution which can handle both busbar systems into one solution?
The Eldon answer for the ABB and Jean Muller Vertical cassettes
In close co-operation with both ABB and Jean Mueller, Eldon has developed a ready to use market solution for both types of cassettes. The SL-fuse disconnector of JM and the InLine cassette of ABB. The new enclosure type is called MCBAxxxxV for Vertical mounting of the units. Customers who are buying the Eldon Multi-Flex® solution can decide either to build-in the IP20 protected busbar system or the standards flat copper busbar solution. Both will fit.
