AU-100 Auxiliary Contact Block 2 Contact 1NC + 1NO Side Mount
Contactor auxiliary contacts are functional accessories designed to work with the main contactor unit.
By providing additional Normally Open (NO) or Normally Closed (NC) contact sets, they enable signal transmission, status feedback, and equipment interlocking within control circuits.
Their core function is to expand the control capabilities of the contactor, meeting the demands for precise operation and enhanced safety protection in electrical systems.
