    Supplementary DC overcurrent protection within equipment, where branch-circuit protection is already provided or is not required by the applicable design. Not a universal replacement for branch-circuit protection. No residual-current protection, surge diversion or AC rating is implied. This white SL7-63 non-polarized revision is not the gray SL7N-63; their voltage-qualified capacities differ.
