Procedures
1Circuit breaker catalog number lookup operation
⚠ If the first 3 letters are PJP, start the search with PJ only.
⚠ If the catalog number starts with N, skip the N and begin the search with the second letter.
- Locate the circuit breaker feature code or part number.
- Use the charts to find the corresponding manufacturer circuit breaker catalog number.
- Use the first letter of the catalog number to determine the breaker frame (if first letter is N, use the second letter).
- Follow the corresponding website link to find the breaker catalog number description.
- Search the catalog using the first 3 letters and first 5 numbers of the breaker catalog number.
