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.
| System | Interrupting rating |
|---|---|
| 240 V AC | 65 kA |
| 480 V AC | 25 kA |
| 600 V AC | 18 kA |
| 250 V DC | 10 kA |
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
Send all identifiers shown on the installed label with your parts requirement for review.
- 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
Send the number and photograph with your parts requirement for EI review and a quote.
