figure are the switch contact postions when the
Auto Trip Indicator is "in" (reset).
NOTES:
1. This wiring diagram includes some optional features
not found on all K-Line Plus breakers, including an
alarm switch, undervoltage trip device, LET/LEC,
and spare auxiliary switch contacts.
2. Secondary disconnect numbers begin with a letter
which indicates in which plug the disconnect
resides. The "A" plug is the right-hand plug when
viewed from the rear of the breaker.
