Arc suppressors

NOsparc arc suppressors from Arc Suppression Technologies (Bloomington, MN) are designed for both AC and DC power applications. The AC products are currently produced to operate between 100-V AC and 480-V AC while DC products operate from 12-V DC through 250-V DC. The company claims the devices suppress 99.9% of the electrical arcing in relays, which increases their operational life and saves the cost of up to nine replacement relays, as well as protects the associated motors from failing. This off-the-shelf technology is easy to install, says the company. Widely used in applications including railway operations and precision manufacturing, the Oshkosh Striker aircraft rescue and fire fighting vehicle recently became the first commercial vehicle to use NOsparc arc suppressors.
