DESCRIPTION
The TEL185B/E is a two-stage transient voltage protector that provides primary and secondary protecton against lightning, inductve switching and electrostatc discharge (ESD) transient threats. The frst stage diverts the transient current through the ground terminal return path and the second stage clamps the voltage to a safe level without interrupton of service.


FEATURES
• Compatble with IEC 61000-4-2 (ESD): Air - 15kV, Contact - 8kV
• Compatble with IEC 61000-4-4 (EFT): 40A - 5/50ns
• Compatble 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 Protecton
• Permanent Two-Stage Protecton
• Subnanosecond Response Time
• Automatc Reset - Does Not Interrupt Service
• Effectve Against Lightning, Inductve Switching and ESD


APPLICATIONS
• Telcom Equipment Connected to Telcom Lines
• Line Connected Modems and Fax Machines
• Remote Telephone Extensions
• Private Wire/Leased Phone Lines
