Contactor-fuse combinations 3TL62/63/66 are typetested units consisting of contactors and HV HRC fuses. With this combination, no additional space must be planned for HV HRC fuses, and thus no additional conductor between contactor and fuse, as this is all integrated in the  combination as one unit, e.g. for switchgear panels.

The combination of contactor and fuse offers a solution based on minimum space requirements. The arrangement of the components on the base plate provides for optimum ventilation and thus, a high normal current, supported by the especially developed fuse holder which ensures a uniform distribution of the current. Even high requirements regarding the dielectric strength – as requested in countries like China – are fulfilled with this design.
