Square D special breaker?

[Codyboy]

I have a breaker that feeds part of my aerobic septic system and it will not turn on.
It's a SqD like a QO with the little trip window but has screws on both ends instead of a stab type.
It's not tripping out , it just won't turn on.
I have just bypassed that breaker for now and running the clock and the pump straight off the buss bar.
It's all still protected from the 20A that feeds the whole setup.
What is that type breaker called so I can look for a replacement?
Doubtful a box store would carry it.

Whats going on that there is so much corrosion inside the box? Do you live close to the ocean?

Not close really , maybe 100 miles or less.
I think the corrosion is from the moisture coming in through the electrical conduits that go down into the septic tank for the aerators and sub pump.

I would agree on the source.

Add duct seal.

Yep, those conduits probably should have been sealed with silicone caulk. Too late now.

Yeah if I ever redo it I will.
I would have 20 years ago but figured the septic company that did the install would have.
I do know that there is some silicone in the tank side where the wires are in the conduit.
Not sure if both conduits are siliconed though.

Eta
To clarify, not the side of the tank but inside the tank where the wires exit the conduit.

Is that nmb in the conduit?

May want replace all 3 while you take 1 minute to duct seal the conduits.

Otherwise, it's going to continue degrading.

Actually replacing all the components would be cheap insurance.

Any number of places to buy that breaker online that will be less money.
