Hi Ryan,There is a pin whole through each handle. If I connect the handles together with a pin, they can only be set or tripped as a set. So will this external "ganging" do the same thing?
Thank you,

Our 100 amp din rail is essentially 2 breakers in parallel. So in theory the 2 60 amp breakers "Could" work but. My concern would be that they may not be tripped at the same time where they are not internally ganged. I can't say "Go Ahead" but.

Why not use one of Midnite's new 100 amp din breakers?

Hello Wrenches,
I am installing a Classic 150 controller in an RV with potential 95 amps output at 12 volts. The customer has a Midnite DIN box and wants me to use it for the controller output. I am out of 150VDC breakers but I have two 60 amp breakers. Is it safe and reliable to use the 2 breakers in parallel for this purpose? I can pin the two handles together. There will be other circuit protection at the battery.
Thank you,
