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.

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.
