Isolation: Your Best Investment for Reliability  


Don’t allow stray currents to shut down your production line

In office or home applications, an electrical surge or spike on a data line may be an inconvenience. On your production floor it can be a disaster. Component blowing, card frying voltage surges and spikes can be caused by nearby lightning strikes, transformer and motor starts and other transients. Quality surge protectors are your best protection from these equipment killers.

 Heavy duty surge protectors meet tough IEEE specifications

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
