Siemens QF230A keeps tripping after installation.
So likely you have a 3 wire dryer cord and a 3 wire branch circuit. The dryer neutral is bonded to the dryer frame and the third wire of the dryer plug.
There were code exceptions for dryers and stoves that allowed timer motor circuits to use the neutral as a current carrier and frame ground.
To use the GFCI for the dryer you will be required to add an additional conductor (new 3 wire+ground cable) and separate the neutral to frame bond in the dryer and use a 4 wire dryer cord.
Likely you also have some GFCI single pole breakers and replaced ungrounded receptacles with grounded (another code exception) and they work OK. The dryer and stove are different as there is current on the third wire where as on the ungrounded receptacle GFCI there is no 3rd wire.
In breif, the neutral (current carrier conductor) from the dryer must be isolated from the dryer frame and dryer ground (fault current carrier conductor).
Or just leave it the way it was.
Check with local authority with jurisdiction for local code requirements.

20 amp AFCI
The breaker has gone bad . You no longer have arc fault protection .
Activating shunt trip circuit on vl160n
A shunt is always energized and it has a purpose. The purpose is to bypass some of the load from the main circuit. It would be tripping due to overload

Installing arc fault interrupter with ground fault
If you meant arch fault with ground fault then no, the two types interfere with each other and trip the breaker as one senses an arch and the other grounding.
If you meant ground fault breaker with a GFCI. receptacle, you only need one of the two, either GFCI. breaker or receptacle.
and for circuits, you can put up to 12 devices (i.e receptacle, light)assuming they consume 1 amp each. Anything over 12 amps or 80% of the rating on the breaker, it will trip/reset.
Or if your talking about wires on a breaker then no more than 2 wires recommended. Try adding a junction box outside the panel if your trying to add other branch circuits or tap off of a receptacle.
