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.\r\nhttps://www.horstmanngmbh.com/products/voltage-detectors-and-voltage-detecting-systems/voltage-detectors/bo-a\r\n19100215-5116RM\r\n\r\n\r\nIFDV"
