Switch Description
The Auto-jet
switch provides a unique method of load inter-
®
ruption, producing a laminated jet of air which extinguishes the
arc.
Auto-jet
switches have a heavy gauge steel, all welded base
®
frame that assures proper alignment and eliminates any prob-
lem of switch-to-enclosure alignment. A quick-make, quick-
break stored energy mechanism with heavy duty, long life die
springs provides high speed opening and closing independent
of the operating handle speed. This durable mechanism as-
sures safe load make, 3-time fault closing capability, and load
interruption with the Auto-jet

*The three-time duty-cycle fault-closing rating means that the
switch can be closed three times into rated fault amperes and re-
main operable and able to carry and interrupt its rated load current.
