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.
