AdjustmentsLong-time delay thermal trip: not adjustable.

Instantaneous magnetic trip: continuouslyadjustable, factory set on HI.Blocks show trip range at marked points oninstantaneous dials.

Note1: Operation above 60 Hertz and 50C mayrequire thermal and interrupting derating of the circuitbreaker. Refer to Selection and Application Manual.
