VOLTAGE TELEPHONE PROTECTOR
TEL50B - TEL50E
DESCRIPTION
The TEL50B/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 TEL50B/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.
