Surge Protection for AC Solenoids

Alt text


Today’s increased reliance on very sensitive electronics makes surge protection an important topic for most industries. The Insurance Institute for Business & Home Safety study found that $26 billion dollars was lost due to non-lightning power surges. In addition, there are about 25 million lightning strikes in the US each year that cause between $650M to $1B in losses according to the Insurance Information Institute, State Farm©.

AC Solenoids are a key component of any UL 508A control panel (also known as an Industrial Control Panel or ICP). However, they are usually overlooked due to their limited cost in the overall system yet are integral parts that can lead to costly and disruptive downtime. The AC Solenoids is used to provide lineal actuation for valves and relays in control systems applications found in refrigeration, HVAC, compressed air systems, refineries, chemical plants, power plants as well as commercial, industrial, residential and manufacturing process applications. They are the critical components in the process loop and are sensitive to transient over voltages.

This section will identify the UL 1449 Surge Protective Device (SPD) to efficiently protection your AC Solenoids and increase its reliability.
