Video: What ampere settings are available on PowerPact H, J and L frame breakers?

Issue:
What ampere settings are available on PowerPact H, J and L frame breakers?

Product Line:
PowerPact H, J and L frame breakers

Environment:
This applies to all PowerPact H, J and L frame breakers with any Micrologic trip unit.

Cause:
The product was purchased before the full load current of the system was known and the ampere rating of the breaker needs to be changed without replacing it.

Resolution:
Here are the settings available for the PowerPact H, J and L frame breakers with Micrologic Standard Trip Units.
In = 60 A Ir = 15 20 25 30 35 40 45 50 60
In = 100 A Ir = 35 40 45 50 60 70 80 90 100
In = 150 A Ir = 50 60 70 80 90 100 110 125 150
In = 250 A Ir = 70 80 100 125 150 175 200 225 250
In = 400 A Ir = 125 150 175 200 225 250 300 350 400
In = 600 A Ir = 200 225 250 300 350 400 450 500 600

If Micrologic Ammeter or Energy Trip Uints are used each of these settings may be adjusted down 1A at a time down to the minimum setting using the trip unit display.
Once completed a MICROTUSEAL can be added to the face of the trip unit to prevent tampering of the settings.
  • I-Line L frame circuit breakers with advanced trip units (Ammeter or Energy style) are available only with 400A or 600A sensor.
  • Settings below minimum dial setting is not possible.  Settings above maximum dial setting is not possible.
  • 100% ratings are not available for 600A sensor.
The following video demonstrates how to manage these settings:
