Engineering interpretation
The figures below are maximum family values. The 15 kV and two-tier ranges do not share every current, fault and duration rating.
Verification limits
Verify the exact catalogue table, manufacturing location, type-test evidence and compatibility of any retrofit breaker before engineering approval.
