Electronic Fuse

If a short circuit current of over 250 A is detected, the battery master switch is opened.

When the wake-up signal "15w" from the CAS is detected, then an attempt is made to close the battery master switch again.

This procedure is repeated continually until the short circuit has been eliminated.
