TZD-1NR is the Voltage Limiting Device (VLD) type F. It may also work as type O in specified current range. According to EN-50562-2 it belongs to class 2.2 of VLD.
Primarily, it is intended for use in open group bonding system of 3kV railway traction, where earth-fault may occur, but direct connection to the running rails is unacceptable due to the stray current.
For tramway, metro and depots voltage limiting device TZD-1NR/T is offered, which has exactly the same functionality and parameters except reduced to 60 V triggering voltage.
