CAM SWITCH 39 CHANGE OVER 32A 1-0-2-EMAS
The EMAS 3-pole 32A changeover switch enables safe, direct manual transfer between two independent 3-phase power supply lines, backup generators, or separate load circuits (Source 1 – OFF – Source 2). Featuring double-break silver-alloy contacts, a center OFF isolation position, and a 60^\circ indexing rotary mechanism, it prevents cross-phase short circuits while delivering long-term reliability in industrial distribution panels.
