摘要:
An electronic circuit includes a number of sensors structured to detect an arc flash from an uncontrolled arcing fault, and a trigger circuit, responsive to the detected arc flash, structured to trigger a triggering mechanism and cause a breakdown of a number of gaps within a low voltage arc flash switch.

A slot motor is for an electrical switching apparatus. The slot motor includes: a support apparatus including a support element having a first leg and a second leg located opposite the first leg, the first leg having a first inner surface, the second leg having a second inner surface facing the first inner surface; a plurality of permanent magnets including a first permanent magnet and a second permanent magnet, the first permanent magnet being located on the first leg, the second permanent magnet being located on the second leg; and a number of U-shaped plates coupled to the support element. The first inner surface and the second inner surface are located between the first permanent magnet and the second permanent magnet.
