NOsparc® Arc Suppressors … Every Cycle Counts!™
We founded Arc Suppression Technologies on a single premise:
Arcing is the root of power contact switch failure.
Until now, no one has successfully suppressed and eliminated the arc created during electromechanical switching. This arc is the prime reason for electromechanical relay failure and if arcing is suppressed and eliminated it can fundamentally transform power switching in the electrical industry.
NOsparc® improves the way power is controlled,
saving time, saving money, and improving safety!
NOsparc® technology offers improved economics and performance when compared to any alternative for virtually any automated switching application. In simple terms, NOsparc® improves the way power is controlled, saving time, saving money, and improving safety across the electrical industry.
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 the contacts of EMRs, removing nearly all of the arc energy created during contact opening.
Industrial Applications In: HVAC, Data Centers, Automation, and Defense

Arc Suppression Technologies designs, manufactures, and markets the NOsparc® family of contact arc suppressors that protect relays, or contactors from the destructive arc energy created in power switching. Contact arcing causes significant surface damage to the contact in relays or contactors.
Our advanced arc suppression products virtually eliminate undesired arcing by adding the advantages of solid-state switching to the durability and current carrying capacity of electromechanical relays or contactors. This increases the overall lifetime, reliability, and safety, and decreases environmental impact of today’s power switching products to unprecedented capabilities.
Relays and contactors operating without load current may run 10 million, 20 million or even more operations (cycles). This mechanical lifespan, however, is reduced to as few as a few hundred operations to perhaps 100,000 operations (depending on application) when the relay or contactor is operated under power.
Like a fire suppression system, actively looking for the instant of combustion; our arc suppression products actively look for the occurrence of thermionic ignition induced by current constriction. When detected, the arc suppression active circuitry extinguishes the arc. Arc suppression is not active when the contacts are open or closed. Alternative technologies passively anticipate the arc. They are not actively detecting the instant of arc ignition, limiting their success. The industry has accepted this problem for over 125 years. We now offer a solution.
