AC Voltage Cut-off Switch


AC Voltage Cut-off Switch (ACCS-) protects electrical equipment from overvoltage hazards by instantly disconnecting power to the load when the operating voltage surpasses the set threshold. Power is automatically resumed when voltage returns to nominal levels after a specified duration or delay.

(AC Voltage Cut-off Switch, protects against voltage swells but not surges.)

  • Instant AC over voltage disconnect. Protect sensitive electrical loads from voltage swells
  • 200ms reaction time
  • High cutoff accuracy, ±1VAC
  • Disconnect up to 1200Amps
  • User specified power-on delay
  • Panel relay style, din rail mountable with bracket
  • 1 year warranty

Available AC Cut-off Voltages:

80, 85, 90, 95, 100, 105, 110, 115, 120, 125, 205, 210, 215, 220 VAC. Other ratings are customizable.

Available Overvoltage Cut-off Types: 

  1. relay on/off for direct AC line cut off, 5Amps

  2. open-collect on/off for 5-24VDC control signal cut-off (eg. for PLC, SSR). 

  3. cutoff up to 1200Amps by using in conjunction with solid state relays or contactors
