Can ground fault be disabled on a 6.0 (A, P, or H) trip unit?

Issue:
Can ground fault be disabled on a 6.0 (A, P, or H) trip unit?
 
Product Line:
Micrologic, Masterpact, Powerpact
 
Environment:
Products sold in North America
 
Cause:
Need to disable ground fault on a breaker with LSIG trip functions
 
Resolution
No. To eliminate ground fault protection, replace the trip unit with a 5.0 type.
For ground fault alarm, they need to replace the trip unit with a 5.0P trip unit (S163A) and use a M2C (S64273) or M6C (S64204)programmable contact module. If replacing a standard trip unit (not A, P or H), the 12-pin connector for the trip unit (kit S33101 for Masterpact, S33100 for Powerpact) must also be ordered.
See instruction bulletins.
