Products tagged with 'earth-leakage add-on protection module vigipact'

This is a Vigi add-on module for ComPact NSX 250 that provides earth-leakage protection. It is used for 4-pole circuit breakers. The operational rated voltage is between 200 and 440 VAC at 50 and 60 Hz. The earth-leakage sensitivity is adjustable from 30 mA to 30 A. It is installed directly on the device terminals and directly actuates the trip unit in case of an earth leakage default. This Vigi add-on module is self-powered internally by the distribution-system voltage, even though it is supplied in only 2 phases. It is compliant with the IEC 60947-2 standard, Annex B.
