Siemens TFAK35 Fuse Accessories

Siemens TFAK35 is a VB SW T FUSE ADAPTER KIT for Vacu-Break panelboard units, delivering a 600 V, 100 A T-fuse connection per pole in a compact low-voltage protection accessory. Supplied as a single-piece kit with one lug per pole, it accommodates conductor sizes from #14 AWG to #1/0 AWG and is intended for use with 17" Vacu-Break panel accessories to extend the fuse range without replacing the panel itself. The hardware included in the kit enables mounting and electrical connection of a T fuse within the Vacu-Break system, aligning with Siemens’ VB fuse accessory lineup for customized protection configurations in industrial controls and distribution panels. Ideal for applications requiring per-pole T-fuse protection up to 600 V and 100 A, the TFAK35 supports flexible conductor terminations on each pole, helping engineers tailor protection to the specific wiring scheme while maintaining compatibility with existing Vacu-Break infrastructure.
