Can you get ground-fault alarm-only (without tripping) on Powerpact H, J, and L frame breakers with electronic (Micrologic) trip units?

Issue:
How to get ground fault alarm only on Powerpact H- J- or L- frame circuit breakers?
 
Product Line:
Molded Case Circuit Breakers
 
Environment:
Powerpact H- J- L- Circuit Breakers
 
Cause:
Circuit breaker replacement
 
Resolution:
No, you cannot get GF `alarm-only` with these breakers.  Alarm with trip is possible; the alarm has three possible indications:
-Reading on the front display module or on a PC through the communication network
-System remote indicators using SDx relay with two output contacts for alarms
-Micrologic trip unit built-in LCD display
 
To get GF alarm-only, you would have to use an external GF relay such as Vigirex with associated sensor and indication hardware.
