Description: DIN dimension fuses to Specification DIN
43625 covering current-limiting fuses with performance in
compliance with IEC 60282-1. These are in accordance with
the R10 and, in some cases, the R20 series of preferred
numbers.
Agency Information: The spring operated striker pin has a
travel and energy output in compliance with the requirements
of DIN 43625 and IEC 60282-1. Complies with IEC 60282-1
and VDE 0670 Part 4.
Dimensions: See Basic Catalog Numbers table.
