  • Our ACST series are over-voltage protected triacs that protect themselves by folding back and leading current into the load when subjected to an overvoltage.
    This feature and the well-dimensioned 10 to 35 mA gate versions as well as its 800 V, 4 to 16 A range make this series ideal for appliances or equipment plugged in 24/7.
  • Featuring 800 V and 5 mA gate rated devices, our ACS™ AC switches, also with overvoltage protection, are smaller devices with highly inductive load switching capabilities for home and irrigation appliances including solenoid actuators and pumps.

AC Switches belong to our STPOWER family.
