DC power circuit
Yes, 75 VDC (125 VDC for D115 & D150) per pole which means that through a four pole device breaking 300 VDC is possible by wiring all four power poles in series. However, be aware that the device current ratings will differ according to the number of poles in series and the type of application.
Devices are suitable but not UL Listed for DC applications.
More information on their DC ratings can be found in the current TeSys Motor Control and Protection Compentns catalog: https://www.schneider-electric.us/en/download/document/MKTED210011EN/
