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.

Description

Features and Benefits

Low voltage overshoot

Low on-state voltage

Does not degrade with

use

Fails short circuit when

surged in excess of

ratings

LCAS specific tip and

ring thresholds
