SRC DEVICES TWO 2 ELECTRODE ELECTRODE HIGH HIGHVOLTAGE VOLTAGE SURGE SURGE ARRESTERS ARRESTERS CG3 Series DESCRIPTION SRC Devices 2 electrode high voltage CG3 Comgaps (1.0 - 8.5 kV) are designed for surge protection in applications for which bias voltages or signal levels of several hundred volts are normally present. Comgaps function as switches which dissipate a minimum amount of energy and therefore handle currents that far surpass other types of transient voltage protection.
