Replace suffix “G” with “W” for no line and load terminals.
2
For two-pole applications, use two outer poles.
3
Neutral protection is indicated by the fourth character: 4 = 0%, 7 = 100%, 8 = adjustable 0–60% and 9 = 0–100%. Neutral is on LH side.
4
320/630 amperes is not a UL or CSA listed rating. 600 amperes is the maximum UL and CSA rating for the LG.
5
Adjustable thermal units are typically used in IEC markets and are not UL or CSA listed.

Rear fed terminals allow the cable to connect to the breaker
from the back instead of the top. Terminal shields or interphase
barriers are included with each rear fed terminal kit (depending
on frame size). When catalog number starts with a 3, it indicates
a kit with three terminals in each kit. Catalog number beginning
with a TA indicates one terminal.
Multiwire Connectors
Field-installed multiwire connectors for the load side (OFF) end
terminals are used to distribute the load from the circuit breaker
to multiple devices without the use of separate distribution
terminal blocks.
Multiwire lug kits include terminal shield, mounting hardware,
insulators and tin-plated aluminum connectors to replace
three mechanical load lugs. UL listed as used on the load
side (OFF) end.
