Product Spotlight: Mersen Surge Protection

Did you know that power related fluctuations cost US companies more than $80 billion a year? Down machines cost you money, time and resources. Instead of spending thousands of dollars to fix or repair your expensive machinery, for a minimal investment, you can protect your sensitive equipment, or your entire facility, from electrical surges.

Most surge spikes occur from within a customer’s own facility. Nearly 80% of all surge problems are directly attributed to power disturbances from a facility’s own equipment. So who is at risk for a surge spike? If you have a facility with motors that are stopping and starting, load panels being turned on and off on a regular basis and other potential power disturbances, then you are at risk for damage.

What types of damage can a surge cause to a facility? Can it really be that bad? The short answer is YES and can be described by the 3-Ds.

  • Disruptive: A surge enters an electronic component, which then in turn, interprets the valid logic command. The result is a system lock-up, machine malfunction, leading to faulty output or corrupted files.
  • Dissipative: This is a repetitive pulsing of short duration energy, which results in long-term machine or system degradation, leading to system replacement sooner.
  • Destructive: This is caused by a high-level energy surge that immediately results in equipment failure, or complete destruction.

Protecting your equipment, and facility, is more important now than ever. At French Gerleman, we carry the Mersen Series SPD units: STXH, STXR, STXP and STXT. Here’s a description of each and how they can help you.
