Transi-Trap Surge Protectors are gas surge arrestors designed to protect
sensitive electronic equipment from damage due to excess voltage or currents
generated by transient phenomena (lightning or static buildup).

The elements in the Arc-Plug(tm) Cartridge consist of two metal electrodes
hermetically sealed in a rugged gas filled, ceramic cylinder. They perform as
voltage-dependent switches which can reliably and repeatedly carry large
currents for brief periods of time. In operation, a sufficient voltage across
the element cause an arc form between the electrodes, changing its impedance
from greater than 10,000 meg-ohms to a few milli-ohms in less than 100
nanoseconds time. While conducting in the arc mode, the voltage across the
surge arrester is less than 30 volts.

The life of the Arc-Plug(tm) Cartridge is a function of the surge current
amplitude and the duration to which the device is subjected. Transients are by
their very nature unpredictable in magnitude and energy level. Life may be
hundreds of operations, depending on surge current wave shape.

After a sufficient number of lightning pulses have been discharged through the
Arc-Plug(tm) Cartridge, there is a gradual lowering of breakdown voltage and
insulation resistance. Therefore, the Arc-Plug(tm) Cartridge replacement is
indicated by an increase in VSWR during transmitter tune-up, or by a "dead"
receiver caused by an extremely strong near-miss lightning discharge shorting the Arc-Plug(tm) Cartridge. In this case, the short continues to protect the equipment until cleared.

Replaceable Arc-Plug(tm) Cartrdige: After hundreds of protective firings of
the Arc Cartridge or after a catastrophic surge, the Arc Cartridge may fail
requiring replacement. Failure of the Arc-Cartridge will be apparent due to
the fact that it fails in a shorted or "fail-safe" mode so as not to leave the
equipment unprotected. The TT3G50 surge protectors are designed to allow the
quick and simple replacement of the Arc-Cartridge in the field without the use
of tools and without removing the surge protector from the circuit. Simply
unscrew the failed cartridge by gripping the knurled section and turning
counter-clockwise. Replace with a new cartridge tightening only by hand until
the cartridge O-ring is fully seated into the body of the protector. The
TT3G50 is no restored to full operation.
