The Vantage provides visible break on both load break and fault interrupting ways. The switch can be ordered with 12.5kA or 25kA symmetrical interrupting. Open / close switching with integral ground position simplifies system grounding procedures. Large viewing windows help verify switch contact position for operating personnel.
