UL 497 Test for Safety Guards for Dual Conductor Communication Circuits

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of UL 497 testing. This standard contains guidelines for testing single and multi-pair air gap arresters, gas cylinder holders, or solid state arresters with a communication circuit protector, fuse-unfused, or other voltage-limiting devices.

The purpose of a circuit protector is to protect equipment, wiring, and personnel from the effects of lightning over-potentials and currents on telephone lines, contacts with power conductors, power induction, and rises in ground potential.

This standard covers protectors designed to limit transient overvoltages and surges in dual-conductor communication circuits such as telephone lines and data communication lines.

Compliance with the UL 497 standard is often required by regulatory and industry bodies and is often a prerequisite for the sale and use of shields for dual-conductor communication circuits. Manufacturers of these protectors typically require UL certification to demonstrate compliance with the standard and to ensure the safety and quality of their products.
