Measuring relays for current monitoring

Current relays for monitoring over- and undercurrent

Current relays are electronic measuring relays for monitoring alternating and direct currents for exceeding or falling below a set threshold value. Depending on the version, one or more loads can be monitored with one device. Special applications where measuring relays can be used for current monitoring are stone and woodworking machines and wherever it is necessary to monitor over- or undercurrent. Measuring relays for current monitoring are characterised by a wide range of monitoring functions in a compact design.
