1
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.
