Siemens GF323N Safety Switches

Siemens GF323N is a 3-pole enclosed fusible general‑duty safety switch (VBII family) rated for 100 A at 240 V AC on 50/60 Hz three‑phase circuits. It uses a 4‑wire configuration with a solid neutral, enabling safe isolation of motors and other loads in indoor panels. The device features a Type VBII enclosed steel housing (Type 1) and a three‑pole single‑throw contact arrangement to interrupt current to the connected load. As a general‑duty disconnect, the GF323N is designed for straightforward isolation points in commercial or light industrial power distributions and supports field‑fusible configurations within the VBII family. In typical Siemens reference data for 240 V configurations, mechanical service life is around 10,000 switching cycles, and the operating temperature range spans approximately −29 °C to +49 °C. Common applications include motors, fans, pumps, conveyors, and other equipment that require a reliable, code‑compliant disconnect in indoor electrical systems.
