For railway overhead contact wires

Product Features

  • VDE version – according to VDE 0681-6
    IEC version – according to IEC 61243-1 category S
  • Pluggable system – minimal setup
  • Integrated self-test – greater safety
  • Light weight – easy handling and transportation
  • Indoor, outdoor and wet weather – one product for all applications
  • Length of 4.7 m – voltage detection from the ground

The BO-A 2.0 is a voltage detector for medium voltage railway overhead contact wires. It is designed to detect the absence or presence of voltage during maintenance work for example. The voltage detector BO-A 2.0 is especially developed for 16.7 Hz networks. If the voltage detector BO-A 2.0 is used in network with a deviating frequency, a visual and audible signal is activated. In this case the network situation must be verified.
The BO-A 2.0 is designed according to IEC 61243-1 resp. VDE 0681-6, depending on the version. The voltage detector is ready for the international market.
According to the German accident prevention standard DGUV Regulation 3 (Table 1c), the device is subject to maintenance tests with minimum intervals of at least 6 years.
