DESCRIPTION
The TEL185B/E is a two-stage transient voltage protector that provides primary and
secondary protection against lightning, inductive switching and electrostatic discharge
(ESD) transient threats. The first stage diverts the transient current through the
ground terminal return path and the second stage clamps the voltage to a safe level
without interruption of service.
The TEL185B/E is designed to protect telcom lines from common mode (line-to-
ground) transients. There are four (4) independent lines referenced to the ground
terminals.
