Peak Let-Through Curve Microswitch indicator ordered separately. See accessories on pages 185-186. For fuse curves see page 134. Rated Current The rated current of this fuse range has been given with 2 copper conductors that have a current density of 1.3 A/mm (IEC 60269-4). For conductor cross section according to IEC 60269-1, the fuses must be derated. Please contact Cooper Bussmann for application assistance.
