Siemens VBNFS363 Panel Mount Disconnect Switch

Siemens VBNFS363 is a three-pole, non-fusible panel-mount disconnect switch in the VBII family, rated for 100 A and suitable for 600 VAC and 600 VDC circuits. Designed for panel installations, it uses a visible-blade design that provides clear open and closed indications and quick-make, quick-break operation to isolate three-phase power reliably. This panel-mount disconnect is intended for main or branch circuit isolation in industrial control panels, machine enclosures, and distribution panels, where compact mounting and straightforward serviceability matter. With a 600 V class rating for both AC and DC, the VBNFS363 supports typical industrial applications such as motor starters, feeders, and control circuits in manufacturing environments. The device is UL Recognized and CSA Certified for use in appropriate panelboard and enclosure installations, aligning with common safety and compliance expectations in North American electrical installations. As part of Siemens’ VBII visible-blade disconnect line, it offers robust mechanical construction designed for frequent operation and easy integration with standard panel hardware.
