The Asymmetrical Discrete Series are SIDACtor ® devices
designed to protect LCAS (Line Circuit Access Switch)
devices from damaging overvoltage transients.
The series provides a specialized asymmetrical
overvoltage protection solution that enables equipment to
comply with various global requlatory standards.
