90Vdc miniature circuit breaker installation

[jinqwem]

Hi, i am looking to install a double pole MCB , like the siemens one into a dc circuit which will have 30 A current and 90Vdc voltage passing,
anyone know how to connect the MCB ?
From the research i done, it seems that connecting them together like the pic is the common way.

Hi Mate,
The question sounds so easy to answer I think we are all waiting for the punch line.
But every question deserves an answer so go on I'll bite,
if all you are looking to do is isolate the battery module from the Cpu with a DP Mcb then that's the way to do it.

Not CPU but PSU, power supply unit,
I intended to used the power supply unit with dc output 90Vdc to charge the battery module,
just that the concept of connecting mcb in negative leg of the circuit seem a bit odd to me...
thanks anyway...

I knew I would get that wrong ........
