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.
