12.1 Technical overview
The technical overview lists all the operating data and dimensions as well as the possible
overcurrent tripping methods and the switching capacities of the SENTRON VL circuit
breakers. The RCD blocks overview contains the relevant operating data.

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".
