FA247065
28 September 2021
Issue:Mission Critical breakers
Product Line:Circuit Breakers
Resolution:
The trip curves and adjustments for the standard and W trip units are the same. The difference is that the W trip units have been modified to delay longer before tripping (though still within the curve) in order to provide more withstand capability and coordinate with downstream breakers at higher fault levels.
More information on the trip units can be found in the
instruction bulletin 48940-310-01.
