05049 Only One Name Means ProTek’Tion™ PBX LOW 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.
