Device for protecting electrical network e.g. on-board vehicle, has isolator with associated, mutually independent triggering units, each of which can cause isolator to switch network off and has separate driver

摘要

The device has a switch-type isolating device (17) near the network connection region that is triggered in the event of a response. The isolating device has at least two associated, mutually independent triggering units (3,33;4,44), each of which can cause the network to be switched off via the isolating device, which respond to different drivers and that contain active triggering elements in series with triggering resistances.
