Auxiliary switch 1W for cylinder fuse base size 22x 58mm to display the switching status of fuses with striker pin indicator SENTRON cylinder fuse system for selective system protection. Siemens cylinder fuse inserts and fuse holders are suitable for use in industrial systems. They are standard in Europe and tested and approved as fuse disconnectors but are not intended for switching under load. Siemens offers an extensive portfolio for switching under load, e.g. 3KF. The Siemens cylinder fuse systems are characterized above all by: 1. Compliance with the standards IEC 60269-1, -2 and -3. 2. Compliance with the standard UL 512. 3. Fast fuse replacement thanks to space for spare fuses in the drawer. 4. Fast detection of the blown fuse thanks to a flashing LED in the event of a blow.
