Overview
05050 Only One Name Means ProTek’Tion™ TELEPHONE INTERFACE PROTECTOR TEL185B - TEL185E 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.
TEL185B TEL185E FEATURES • Compatible with IEC 61000-4-2 (ESD): Air - 15kV, Contact - 8kV • Compatible with IEC 61000-4-4 (EFT): 40A - 5/50ns • Compatible with IEC 61000-4-5 (Surge): 95A, 8/20µs, Level 4 (Line- Gnd) & 48A, Level 4 (Line-Line) • Designed for ±185 Volt (Peak) Telephone Lines • 4 Wire, Line-to-Ground Protection • Permanent Two-Stage Protect...
