    ARW1 Highlights

    Several components work together in an ACB. One of the main features is a blast valve. When the arcing contacts separate and the arc forms, the blast valve opens arc chutes. Pressurized air pushes through the arc, disconnecting it from the contacts.
    The pressurized air pushes the arc towards arcing probes and rings. These are conductive elements that help to move the arc away from the contacts. As the arcing contacts get farther apart, the arcing probes and coils get closer together, allowing them to attract the arc.
    The arc is moved into the chutes toward an arcing electrode. Eventually, the arc is pushed through the chutes and stretched until it is completely eliminated.
