Description

A method and apparatus for a protective device for indicating when ground fault protection is not being provided by the protective device. The protective device includes source and terminals between a conductive path and face terminals. The protective device further includes a latching mechanism, adapted to be operable between a first state in which the latching mechanism permits electrical contact between the source terminals and the load terminals and a second state in which the contact is broken; an alarm indicator, adapted to provide an indication that the protective device is not providing ground fault protection; and a fuse, adapted to blow when the latching mechanism fails to open during a manual test of the protective device.

Dispositif et méthode concernant un dispositif de protection pour indiquer lorsqu'une protection contre toute anomalie de mise à la terre n'est pas assurée par le dispositif en question. Ce dispositif comprend une source et des bornes entre un circuit conducteur et des bornes en pointes. Le dispositif de protection comporte également un mécanisme de verrouillage, adapté de façon à pouvoir être actionné entre un premier état où le mécanisme de verrouillage permet un contact électrique entre les bornes de la source et les bornes du consommateur, et un second état où le contact est coupé; un indicateur d'alarme, adapté de façon à donner une indication que le dispositif de protection n'assure plus une protection de mise à la terre, et un fusible, adapté de manière à fondre lorsque le mécanisme de verrouillage ne s'ouvre pas lors d'un contrôle manuel du dispositif de protection.
