M11-F

Furnace switchgear in withdrawble 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 switchgear fulfils the norm IEC62271-200 and can optionally be equipped with a pressure release duct.
