Can I install it instead of a QP breaker?

Depends on the load center you have if the dual function plug on neutral breaker will work need to know the load center part# to confirm.

Can this be used with PN2040B1150C/PN2040L1150C load center?

I apologize; this breaker is the neutral plug-on type, so the panel is supposed to be designed for the installation of this type of breaker, Make sure this load center is just like that.

Will this work on siemens mc4040b1200secw load center

If you label lists QAF & QPF types then yes you can use the dual function breaker.

Will the simens q115dfnfit in the wfco 8955pec panel ?

Siemens breakers are UL approved and tested to be used in Siemens panels only.
