Three Pole and Four Pole Units
The three pole structure consists of three single pole units
assembled with an internal mechanical interlock which
actuates all units simultaneously. The units are available
with either a single toggle handle or with a handle per pole.
Units with four pole construction operate with a minimum
of two center toggle handles or with a handle per pole.
Please see decision one of the part number decision tables.
Mixing of delays, ratings and configurations is available in
each individual pole. The auxiliary switch is offered in any
series trip pole.
Breaker poles are numbered consecutively when viewed
from the terminal side, with the ON position up, starting with
pole #1 on the left side and proceeding to the right.
