M11-F

Furnace switchgear in withdrawable unit design

up to 40.5KV

Our furnace switchgear M11-F in withdrawable unit design is used for the reliable operation of your ladle and electric arc furnaces. The switchgear can also be offered with two parallel frequent-operated circuit breakers for higher transformer nominal currents. Our withdrawable unit design ensures a very fast exchange of the furnace switches and thus only short downtimes in case of an error.

The M11-D switchgear, type-tested in its basic version, complies with the IEC 62271-200 standard. Optionally, the M11-F can also be equipped with a pressure relief channel.
