lightning surge protection devices are designed for
the rugged industrial environment. Products range
from the standard factory floor signals such as 4-20mA,
thermocouple, RTD and strain gauge to filtering and
protecting the AC Power in instrument panels.
lightning destroys many millions of dollars of sensitive
electronic equipment. Millions more are lost through
extended down time and the loss of production or mission-critical
information. That's why companies around the world
depend on in-line M-RESTER Lightning Surge Protectors
to protect both signal and power wires. M-System offers
superior protection and selection across a side range
nuts and bolts of the world's best Lightning Surge
Protects sensor, signal and power
Superior protection and selection
across a wide range of applications.
M-RESTERs can be removed and
tested without disconnecting wires.
Base socket connects input/output
signals when an element is removed.

Lightning induced surges occur in a cable as a result
of rapid and violent changes in the magnetic field
intensity generated around the cable.
The surge propagates in the cable, and instantaneously
applies high energy to the electronics equipment
connected to both ends of the cable. Interline breakdowns
occur when electronic components are directly hit
and destroyed by lightning surges generated between
two cable conductors connected to the equipment.
In discharge breakdowns, a lightning
surge creates a very high potential difference between
two conductors and ground.
As a result, a discharge occurs between some parts
of the circuit and areas electrically grounded,
such as the metal housing. Electronic components
are damaged by some of the discharge current that
flows through the circuit.
The effects of induced surges on connected equipment
are more severe when the connecting cable is longer;
the induced current is higher; or the equipment
is located closer to the site of the lightning strike.
