Series M6: Protected type SWITCH BOARD
The M6 series is made up of protected medium-voltage compartments for interiors of the modular type and suitable for the realization of any medium-voltage electric secondary substation layout.The compartments of this series, having smaller dimensions, can be used in confined spaces; furthermore, having the SF6 insulation can be used in environments with more onerous environmental conditions (salt areas, heavy industrial areas, areas with dust).
In addition, the compartments of this series are equipped with internal arc seal for greater safety of the staff responsible for the maintenance of the substation.
They are made according to the CEI EN IEC 62271-200 Standards to achieve maximum safety, reliability and continuity of operation.
Main features:
- Air insulation mixed gas SF6
- Rated voltage up to 24 kV
- Rated busbar current up to 800 A
- Rated output / input current up to 630 A
- Rated short circuit current up to 16-20 kA
- IP3X degree of protection
- RAL 7030 painting
- Internal arc sealing up to 16 kA for 1 s.
Further technical and dimensional data can be found in the specific M6 catalog (*)
ENEL DY803 series: Protected Switch board with load break switch gas SF6 insulated

SF6 insulated switch disconnectors and load break switch
The load break switch and switch disconnectors of this series are designed for easy installation in MV distribution boards, with the highest performance of SF6 gas.The maintenance and checking operations are extremely simplified for the extractability on guides and for the frontal arrangement of the control.These devices allow complete metalic segregation between the busbar compartment and the lower compartment.
Main features:
- SF6 insulation;
- Voltage up to 24kV;
- Bus current up to 630-800A;
- Short-circuit current up to 16-25kA
- Standard IEC 62271-200
