  Rated direct current data apply only for thermomagnetic overcurrent trip units. The values apply for at least 3 conductor 
paths in series and extremely high switching capacity "L". For switching direct current, the maximum permissible direct 
voltage per conductor path must be observed; see also "Suggested circuits for DC networks" in the Chapter "Application 
planning".
