Dold Phase Monitoring Relay, 3 Phase, DPDT, DIN Rail - IL9075.12/001 AC50-400Hz 400V

Fuse monitor, IL9075/001. Recognises fuse failures in three-phase networks up to 440 V Failure notification even with loads switched off Usable for all types and sizes of fuses Independent of rotational direction No abnormal behaviour even in asymmetrical networks with harmonics, or with regenerative motors Shorter response time than motor protection circuit breakers Internal resistance >1 MO Rest current principle 2 LED displays 2 changeovers 35 mm overall width. The IL9075/001 monitors all three fuses in the three-phase network to produce, for example, an automatic shutoff and switch lock of a three-phase motor if one or more of the phase fuses fails (in accordance with IEG 55, VDE 0435).
