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.
3. The spare auxiliary switch contacts which are routed
through secondary disconnect “A” are standard on
EO breakers. Those routed through plug “B” are
optional.
