Arc chuteEvery man who ever faced electricity knows phenomenon of a spark while breaking and connecting switches contacts, chopper switches and buttons. Moreover, the stronger the electrical circuit, the more powerful and destructive is spark.Special assemblies called arc chutes are used to prevent burning and rapid quenching of electric arc in various electric commutation devices.Arc chutes is a set of metal plates of particular form, fixed at certain distance from each other, between two plates made of dielectric.Permanent magnets or electromagnets are also used in high power arc chutes to improve the draw of electric arc. Electric arc emerging when breaking contacts, as is known, follows the path of least resistance. It is drawn into the slots of arc chute plates, where plates cut it into several smaller arcs and thus it cools and fades faster.In arc chutes with magnetic blast made on permanent or electromagnets, the arc is drawn quickly into the chamber due to exposure to magnetic field formed by these magnets. Arc quenching in air circuit breakers occurs due to the flow of compressed air.Design of air circuit breakers vary depending on the rated voltage, ways of creating insulating gap between contacts, as well as ways to supply compressed air into arc chute assembly.
The multi-channel device circuit breaker boards are used in, for example, series machine production or in control and process technology.
