Powerpact L circuit breakers with 250A sensor
No, the 250A Powerpact L Circuit Breaker is not available with Ammeter or Energy Trip Units. It is available only with the Standard Micrologic Trip Units 3.3 and 3.3S (breaker catalog number suffixes U31X and U33X, respectively). There are, however, other options to consider that may meet the job requirements.
Use a 400A Powerpact L breaker. It is available with Standard, Ammeter and Energy trip units, and it can be field adjusted from 400A to 250A (125A minimum).
Use a 250A Powerpact J Circuit Breaker. It is available with Standard, Ammeter and Energy Trip Units, and can be field adjusted from 250A maximum to 70A minimum. Note that since the J is smaller than the L, make sure it is suitable for your application (enclosure, lugs, etc.).
