functions:
-Auxiliary power alarm Loss of the auxiliary power supplying Vigirex relays is indicated by a LED on the front of the device and by the operation of a fail-safe alarm contact.
-Discrimination and settings c discrimination Discrimination consists in: v dividing the installation into a number of groups of circuits and protecting each group with an appropriate residual current device, v coordinating the upstream and downstream devices such that only the faulty section is shut down.
-Vigirex relays can be set to obtain up to eight levels of discrimination, extending from the final outgoers up to the circuit breaker at the head of installation. I∆n/2 alarm threshold Vigirex type AP relays have an alarm threshold that warns of a non-critical degradation of the insulation, leaving time to carry out preventive maintenance. The alarm threshold is set automatically at In∆/2, where I∆/n is the residual operating current. The alarm is indicated by a LED and operates an auxiliary contact.
