Operating PrincipleBrief HistoryDesign FeaturesGenerator Circuit BreakersHigh Power TestingIssues Related to SF6 Circuit BreakersComparison with Other TypesCurrent interruption in a high voltage circuit breaker is obtained by separating two contacts in a medium, such as sulfur hexafluoride (SF6), having excellent dielectricand arc quenching properties. After contact separation, current is carried through an arc and is interrupted when this arc is cooled by a gas blast of sufficient intensity. SF6 gas is electronegativeand has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high pressure flow of sulfur hexafluoride gas, and an arc is st…See more on en.wikipedia.orgEstimated Reading Time: 12 minsSF6 Circuit Breaker: What Are They?

What Is A Pesticide device?Recognizing A Device by Reading The LabelClaims on Device Labels Or AdvertisingOther Information About Regulating Pesticide DevicesExamples of Regulated Pesticide DevicesExamples of Devices That EPA Does Not RegulateState Regulation of DevicesPesticides are commonly thought of as chemicals. But we also have a role in regulating devices used to control pests. How a device might be regulated, however, depends on the device's specific design and function and whether it is used with a pesticide. A pesticide device is: 1. An instrument or contrivance (other than a firearm) that is used to destroy, repel, trap or mitigate (lessen the severity of) any pest such as insects, weeds, rodents, certain other animals, birds, mold/mildew, bacteria and viruses.
