Siemens 3NW1100-0HG Time Delay Cylindrical Fuse

Siemens 3NW1100-0HG is a SENTRON cylindrical fuse link designed for Class CC protection, delivering a 10 A current rating and a 600 VAC maximum voltage, with a time-delay (slow-blow) characteristic that tolerates brief inrush currents common in motors, transformers, and other inductive loads encountered in industrial panels. The compact body measures about 10.3 mm in diameter and 38.1 mm in length, and it is intended for standard Class CC fuse holders found in industrial control panels and electrical distribution enclosures, allowing straightforward retrofits within existing Siemens SENTRON protectors and compatible assemblies. The part is specified under UL standard 248-4 as a slow-blow fuse, indicating its suitability for circuits up to 600 VAC in North American installations and aligning with common protection schemes in commercial and industrial equipment. Typical applications include motor starters, panel boards, and other control circuitry where overcurrent protection must withstand startup transients while maintaining reliable safeguards against sustained faults.
