NOsparc® Arc Suppressors … Every Cycle Counts!®

Contact arcing is the #1 cause of relay* failure.

Our big idea is a novel patent-protected solution that eliminates contact arcing at its source; increasing contact life 10-times or more.

Relays runs the world! … and contact failure imposes billions of dollars each year in unwarranted, avoidable costs. NOsparc® arc suppressors increase the operating life of contacts 10X or more, yielding enormous cost reductions in relay costs, scheduled maintenance and unscheduled downtime.

Robust, reliable NOsparc products eliminate contact arcing at its source and have immediate uses in thousands of commercial and industrial applications. Never before has there been an off-the-shelf solution that operates across a broad range of AC and DC power applications.

NOsparc® improves the way power is controlled,

saving time, saving money, and improving safety!

Over the last five years, our company has designed, engineered and patent protected a line of NOsparc arc suppressors that are truly revolutionary. This simple yet novel technology eliminates nearly 100% of contact arc energy. The compelling result is that NOsparc arc suppressors extend the operational lifetime of contacts by 10 times or more. In simple terms, if the replacement interval of a relay in a specific application is six months, the addition of a NOsparc arc suppressor would extend that interval to five years, producing cost savings equal to nine relay* replacements in addition to the many hours of preventative maintenance that will no longer be necessary.




NOsparc Family


Our NOsparc® arc suppressors are available in for both AC and DC power applications. We offer the only 2-wire arc suppressor, attached in parallel to relay* contacts, removing nearly all of the arc energy created during contact opening.


Commercial and Industrial Control Applications Include:

HVAC-R, Industrial Automation, Railway Signals, and Precision Manufacturing
