TIPS ON BREAKER SELECTION
If the breaker you order is not
available, consider the following:
1. Breaker with different
or no lug options
Example
LGE3250FAG
Consider: LGE3250FAW
and (2) TA250FJ
2. Higher interrupting ratings
Example
JGS3100FAG
Consider: JGH3100FAG
3. Components vs. kits
Example
Kit: EGHMVD06BO
Consider components:
68C6048G41 Handle
66A6010G95 Shaft
1498D66G17 Mechanism
