ASC Series switches combine a current transformer, microprocessor-based signal conditioner and limit-alarm contact in one package for monitoring or proof-of-operation applications. Calibrated at the factory to users’ specs, the switches provide a magnetically isolated NO or NC solid-state output for control circuits rated up to 135 Vac or Vdc. An LED indicator provides quick visual confirmation of contact status. The switches meet UL, CUL and CE certifications.
