three-stage Din rail Surge protector
HESP4DR
Model HESP4DR meets 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). Five RS-232 signals on terminal blocks are supported with a
clamping voltage of 6.8 Volts.
The HESP4DR is housed in a sturdy DIN rail mount case with a #10
grounding screw. In order to work properly, it is important to have a good
connection between the #10 screw and a solid earth ground.
•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
• Wide operating Temperature
• NEMA TS2

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.
