3 Pole Gas Discharge Tube W/FS 7.5*11m

Description:

Over-voltage transients are often found in communications and control lines. Cause of such abnormal voltages are lightning strikes, atmospheric lightning discharges, accidental contact between power and communications lines, unexpected rise in the supply voltages of the installation as a result of misoperation, and appearance of voltage higher than normal during switching operations. The over-voltage transients, if not properly taken care of, not only cause damage to delicate components such as semiconductors, ICs and others comprised in the equipment itself, but also are highly dangerous to personnel. Thus, protection against over voltages is necessary for high reliability and long life of general electronic equipment. To this end, the importance is the selection of the best arresters for the over-voltage transients. The protectors or arresters much have high current carrying capability and fast response time. Long life, small size and little weight are additional factors of the consideration.
