Acti9 C60H-DC Polarity

[fastbike]

I want to use Acti9 C60H-DC (part A9N61539) inline for a battery electric storage system.

Is this part suitable i.e. the inverter will be accepting current from the battery when discharging, and sending current  to the battery when discharging, so the flow is bidirectional.

Is the device polarised, or can it be used in this application ? I've had some advice that I should wire it with the likely fault current in the direction of the arrow. As the inverter is limited to 10kW, but the battery could output a magnitude more than this , this seems sound advice.

Thoughts ?

Hi,

That's the best non-answer I've had in a long while 🙂
My question was relatively simple: is the device suitable for the use case ? 
As a bonus, if it is not suitable, can you recommend a different device as  a 500V d.c. 50A+ rated DIN rail mounted isolator between a solar inverter and a HV battery.

Hello @fastbike, my thoughts as follows:

I think you can use two Acti9 C60H-DC breakers in series but installed in opposite directions to account for bidirectional current flow. This might ensure that at least one breaker will trip regardless of current direction.

Given the specialized nature of your application, it's still advisable to consult with OEM, Schneider Electric.
