HI or HB, and why it does not matter

The pattern is legible once you line the references up: the last three digits of the GE reference are the ampere rating. If you are holding one of the other five numbers, that is what it maps to.

Reading the interrupting rating correctly

An interrupting rating is not one number, and quoting the biggest one is how people end up misapplying a breaker. For this reference the published figures fall away sharply as system voltage rises.

A Model 1400 MCC commonly sits on a 600 V system, which is where the 18 kA figure applies rather than the 65 kA one. These are catalogue figures published for the manufacturer reference. They are not a measurement of any particular unit, and a breaker that has interrupted a fault is a different proposition from one that has not. Application against your available fault current is an engineering decision on your side of the fence, not ours.

What to send with your request

Both numbers make the identification check more direct because one of them is a live catalogue number.

• A photograph of the breaker label showing the catalogue number and any suffix
• The ampere rating stamped on the handle or the label
• Your system voltage and, if you have it, available fault current at that point
• Whether the breaker is being replaced after a fault or as part of a planned rebuild
• Quantity required, the condition you can accept, and your need-by date

We do not need a purchase order to answer an identification question. Send the number and the photograph and we will tell you what we can establish.
