The BO-A 2.0 is a voltage detector for medium voltage railway overhead lines. It is designed to detect the absence or presence of voltage during maintenance work for example. The voltage detector BO-A 2.0 is suitable for use in 16.7 / 50 / 60 Hz networks. If the voltage detector BO-A 2.0 is used in a network with a deviating frequency, an optical and acoustic 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. DIN VDE 0681-6, depending on the version. The voltage detector is ready for the global market.
