GFPE breakers

NEC 555.35 (A) 3
how are we supposed to protect the feeders for a shore power pedestal? We can't find anyone who sells a 220 volt 100 - 125 amp GFPE breaker. Where can I find these???

The jobs I have inspected used "Marfina Guard" detection coupled with shunt trip breakers.
You might look at "Bender" website or" Littlefuse""

Do you think the industry is moving more toward ground fault monitoring rather than breakers?

The monitor is tied to the shunt trip breaker, so it is a combination as @augie47 posted.

I get that, it's just that I am having an impossible time trying to find a GFPE breaker for a 100 amp feeder.

It’s cheaper for manufacturers, GFPE breakers sit on the shelf for a long time, so using a readily available shunt trip breaker of any amperage, and a monitor that has a wide range amperage’s makes sense from a manufacturing and warehousing standpoint.
