General Description

The 420LE/B series is a two stage transient voltage protector providing 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 420LE/B series is designed to protect data lines from differential (line to line) and common mode (line to ground) transients.

Key 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 4-20mA Current Loops.
  • Automatic Reset - Does Not Interrupt Service.
  • Permanent Two-Stage Line Pair Protection.
  • Common Mode & Differential Mode Protection.
  • Subnanosecond Response Time.
  • Effecti.
