Siemens HF261 Heavy Duty Switch Industrial Grade

Siemens HF261 Heavy-Duty Indoor Fusible Safety Switch is a 2-pole, 2-fuse disconnect rated for 30 A up to 600 V, housed in a NEMA 1 indoor enclosure for general power-disconnection in industrial panels. Part of the VBII safety-switch family, it accepts 480 VAC / 600 VAC or 600 VDC service, with higher-current variants HF262 (60 A) and HF263 (100 A) sharing the same form factor. Within the HF261 family, fuse-type configurations are represented by variants such as HF261J, indicating specific fuse compatibility, while outdoor equivalents carry the HF261R designation. This combination of compact, rugged construction and standard safety features makes it a practical choice for reliable circuit protection and power isolation in commercial or light-industrial environments.
