3 Features Energy-saving and maintenance free High-current transmission in hermeti - cally sealed chambers No oxidation or corrosion in the chambers. Low loss over long-time use The contact will not worsen in an avalanche effect due to heating Bars do not need cleaning 50 Plating not required The torsion spring louver of the MC-Multilam permits the contact for - ce as well as the electrical performance of the busbar joint to remain cons - tant even when the compression force drops to 50% of its initial value Economics of the installation: low re - sistance factor over a long period of time (stable long-term behaviour), minimum energy loses Busbar joints do not need any servicing High operating reliability Substantially prolonged service life Do-it-yourself easy assembly 350 V IEC MC-SEALconTACT ALM Si0.5 EN- AW6060) MC-SEALconTACT MC-SEALconTACT E-AI99.5 EN-AW1350) MC-SEALconTACT Notice: In a corrosive atmosphere and with combinations of different ma - terials, in order to prevent corrosion potential differences should not exceed 350mV. Silver-tin and silver-aluminium combinations should be avoided in a corrosive atmosphere. Also see Technical Report IEC 60943: MC-SEALconTACTs are suitable for unplated or plated connections Cu/Cu, Cu/Al alloys or Al alloys/al alloys (e.g. AlMgSi0.5, EN-AW6060). The busbar material and application should be stated in any inquiries or orders for MC-SEALconTACTs. MC-SEALconTACTs must not be used in connections with Cu/pure aluminium or pure aluminium/pure aluminium (e.g. with E-Al99.5, EN-AW1350) with or without electroplating. The contact re - sistance of a connection with MC- SEALconTACT can rise rapidly, resulting in marked heat generation. 3
