Issue:
Breaker replacement
Product Line:
Q Frame breaker enclosures
Resolution:
Yes, the Q2 enclosures, Q22200NS, Q22200NRB, Q23225NF, Q23225NS, and Q23225NRB, will accept the PowerPacT Q frame circuit breakers. However, restrictions regarding the short circuit rating may apply. The enclosures marked for use with the QBL, QDL, QGL, or QJL breakers are designated series E05. For retrofitting these breakers into existing series E03 or earlier enclosures, restrictions regarding short circuit current ratings apply.
The following statements are on the wiring diagrams of the series E01 and E03 enclosures: "The short circuit rating of this enclosure is equal to the interrupting rating at the supply voltage marked on the circuit breaker installed, but not to exceed 42,000 RMS Symmetrical Amperes at 240Vac." and "Replacement circuit breakers must have an interrupting rating equal to or greater than that of the circuit breaker originally installed".
