Conversion kit for changeover switch I-I+II-II 100-125A

This accessory allows two 3-pole devices (+ additional pole) to be coupled to form a 6- or 8-pole SIRCO M switch-disconnector or a 3- or 4-pole SIRCO M changeover switch. The accessory must be ordered with an external operating handle. SIRCO M changeover switches enable transfer between two power sources (I–0–II) or load transfer between two low-voltage circuits (I–I+II–II) without interruption of supply.
