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

Issue:
Field adjusting trip point of breaker

Product Line:
PowerPact H, J and L frame breakers with electronic trip unit

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.

If Sensor Rating equals...	then available Ir dial settings are...
60 A	15, 20, 25, 30, 35, 40, 45, 50, 60 A
100 A	35, 40, 45, 50, 60, 70, 80, 90, 100 A
150 A	50, 60, 70, 80, 90, 100, 110, 125, 150 A
250 A	70, 80, 100, 125, 150, 175, 200, 225, 250 A
400 A	125, 150, 175, 200, 225, 250, 300, 350, 400 A
600 A	200, 225, 250, 300, 350, 400, 450, 500, 600 A

If Micrologic Ammeter or Energy Trip Units 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.
NOTE: The ampere rating on H and J frame thermal-magnetic breakers can NOT be adjusted, however you can adjust the magnetic trip setting on J-frame thermal-mag breakers.

The following video demonstrates how to manage these settings:
