Hi everyone,

I need your assistance to determine whether the breaker in the attached image is a DC breaker and whether there is a sign indicating that it is for the DC side and not the AC side.

[ElectriciansForums.net] DC or AC breaker
 
The fact it is 3 pole, suggests it is intended for 3ph ac.
Most dc breakers are single or double pole.

It only lists 50/60hz in its rating table

So I would not consider it suitable for DC.
