Surge guard gave up no 50amp shore power

[MTK1946]

My 2011 50 amp surge guard gave up today . Model is a TRC 41250.
Any ideas of what brand to replace it with?
It will operate the generator but no 50 amp shore power. 30 amp works fine, as it should.

I take it this is hard wired in your RV? I had one that was hard-wired up until until I sold that RV. The next time I bought a portable Progressive Industries PT50 and have been using it for the last 10 years with two different RV's. Plus, if it were to go out, you can just bypass it until you get it repaired or replaced. It is an EMS and not just a surge protector. They do have a hard-wired version too. HW50x.
