UTB Special Applications – Universal Transient Barrier

Description

Universal Transient Barrier

The universal transient barrier UTB-TA and UTB-SA are specifically designed to protect telephone / modem circuits.

The UTB15EX and UTB30EX are BASEEFA approved versions for hazardous area applications (ATEX Category II 1G EEx ia IIC T4). They can be inserted without recertification into any IS loop where input <1.3W.

Features

  • General purpose barrier – protection of low voltage circuits and transducers
  • Separate plug and base design – hot swappable feature allows ease of module replacement
  • Multi stage protection – fine over-voltage protection, helps ensure lowest residual surge voltages reach sensitive equipment
  • Common-mode and differential-mode protection – protects against both possible surge conditions
  • Ease of grounding – through DIN mounting rail or via terminal
  • Surge rating to 20kA 8/20µs – ideal for exposed wiring
  • EX series for use in intrinsically safe areas
  • ERICO Surge Products are covered by an extended warranty; see the attached document for more information
