Abstract

A protective device enables reliably cutting a drive region off the power supply of a guided vehicle. The drive region is connectible to the power supply via at least one drive region switch and it comprises stator sections that are strung together. The sections are connectible to a drive region supply line by way of a stator section switch. The protective device has a control unit for opening at least one switch in the event of a malfunction. The object is to provide a protective device that is inexpensive and that allows a flexible allocation of the power supply to the drive regions. For this purpose, the control is adapted to open all stator section switches and the one or more drive regions switches in the event of a malfunction.
