Notes on Schematic Arrangement
Schematics are shown with:
1. Closing Springs Discharged
2. Breaker Open
Note that, in this condition, the trip
latch is free to reset, but is tempo-
rarily blocked until the closing springs
are partially recharged. Prior to full
spring charge, LS3 (NO) closes, and
LS3 (NC) opens.
