MCBs technical details
Use of MCBs in direct current circuits
Use of S 200/S 200 M/S 200 P miniature circuit-breakers consideration, the outgoing circuit may be implemented
in direct current circuits 72 VDC/125 VDC from above or below the device.
In DC systems up to 72 VDC or, as the case may be, series For higher direct voltage up to 440 VDC devices of the S 280
connection up to 125 VDC, customary S 200/S 200 M series UC series must be used.
MCBs can be used.Polarity does not need to be taken into
Example for max. permissible voltages between conductors depending on the number
of poles and type of connection.
SK 0173 Z 99
Examples for different voltages between a conductor and earth where voltages between
conductors are identical:
