three-stage rS-422/485 Surge protectors
485HESP, 422HESP, 232HESP
These three-stage surge protectors meet IEEE 1000-4-5: 1995 and IEEE
C62.41-1991 recognized standards for premium surge protectors. It
protects against lightning strikes, power surges, and other types of voltage
disturbances with three stages of protection for each supported line: a gas
discharge tube followed by a series resistor and finally a Transient Voltage
Suppresser (TVS). Three RS-422/485 signals on terminal blocks are
supported with a clamping voltage of approximately 6.8 Volts.
These surge protectors housed in a tough metal, panel mount case with a
protected signal ground connection and dedicated chassis ground lug.In
order to work properly, it is important to have a good connection between
the #10 screws and a solid earth ground. The 485HESP provides two
terminal posts and two metal mounting brackets to provide a good ground
connection.
•Three stages of protection on every data line
1) Gas discharge tube
2) Series resistor
3) Transient voltage suppressor
• Protected signal ground connection
• Rugged terminal block connections
• Dedicated chassis ground lug

surge Protection standards
IEC 1000-4-5: 1995 “Surge Immunity Test” and IEEE C62.41-1991
“IEEE Recommended Practice on Surge Voltages in Low-Voltage AC
Power Circuits” are the recognized standards for surge protection.
B&B Electronics’ heavy duty surge protectors have been tested at 6
kV to meet these two specifications.
