Protection for Data Lines

Electrical transients can cause equipment to malfunction and can even have a catastrophic effect, inflicting severe damage to expensive devices, some of which may be mission critical. These electrical disturbances can enter into a network system through data lines that create a “back door” entrance to equipment. Normally, these electrical lines transmit data via very low voltage signals between devices, and by their very nature, data cables can have a direct route into equipment when higher voltage transients find their way onto data lines. Such damaging transients include electrostatic discharge, electromagnetic interference, and the most devastating of them all, lightning.

When damage to expensive equipment does occur from these types of anomalies, it is not covered under a manufacturer’s warranty. When you compare the cost of downtime and equipment replacement costs, these surge protectors are an excellent investment.

Minuteman’s LineGuard products are UL listed and designed for fast, simple installation. All models are covered under Minuteman’s limited lifetime warranty, along with a $10,000 attached equipment protection plan.
