Wire breakage monitoring, short-circuit-line monitoring

wire breakage monitoring

The devices of the wire breakage detector series have been developed for monitoring of both driven as well as non driven consumer wires. The proper condition of the wire is signaled through a plus switching malfunction message output, which in case of failure or loss of voltage switches off (closed current circuit).The intact measuring circuit is signaled by a LED in the front panel.
