002540001 is a 1-pole EFD 10 modular fuse holder designed for 10x38 midget fuses without LED indication. It is rated for a maximum voltage and current of 690V AC/DC at 32A according to IEC standards, and 600V AC/DC at 30A per UL specifications. The holder features a modular snap-kit design that allows users to configure different pole configurations by inserting connecting elements into the side slots and assembling them together with a connecting shaft. This fuse holder is commonly used in industrial control panels, distribution systems, and electrical protection circuits where reliable overcurrent protection and modular flexibility are required.
