General Description:
Series connected Surge Protective Device with Encapsulation Technology, Sinewave Tracking Circuitry (STC), 20Ka per mode / 60kA total peak surge current for virtual elimination of ringwave type transients.

Designed for use at ANSI / IEEE Categories A, B, and C with susceptibility up to all exposure levels to protect sensitive/critical loads fed by a single electrical circuit.
Circuit Design: Series connected hybrid design incorporating discrete all mode protection and utilizing encapsulated Sinewave Tracking Circutiry ( STC ) design to provide lowest possible let-through voltages. All suppression circuits are encapsulated in high dielectric compound to promote long component life and protection from the environment and/or vibration. All circuits include component level and thermal fusing.
