Description Technical Specs & Box Contents Drivers & Downloads

IEEE 1000-4-5: 1995 and IEEE C62.41-1991 are the recognized standards for top quality surge protectors. B&B Electronics’ heavy duty units meet these specifications with three stage protection for maximum safety: a gas discharge tube feeds to a series resistor and a TVS (Transient Voltage Suppressor) for each supported line.

Tough metal panel mount cases protect models 232HESP, 422HESP and 485HESP. HESP4DR provides the same surge protection in a molded DIN Rail mount case. All have #10 ground screws which must be connected to a solid ground.

  • Three stages of protection on every data line
  • Protected signal ground connection
  • Rugged terminal block connections
  • Dedicated chassis ground lug
  • DIN or panel mount versions
  • RS-232, RS-422, RS-485 versions
  • Easy to install
