Abstract:
1. A protection device having line and load terminals, the device comprising: a latching mechanism, adapted to move between a closed state which establishes electrical contact between said line and load terminals, and an open state which prevents electrical contact between said line and load terminals; a secondary contact arrangement in a conductive path between a solenoid of the protection device and one of the line terminals; an initial reset prevention mechanism configurable in a first position to establish electrical contact between at least two contacts of the secondary contact arrangement and prevent said latching mechanism from being set in said closed state, and configurable in a second position in which there is no electrical contact between the at least two contacts of said secondary contact arrangement and enabling said latching mechanism to be set in said closed state when power is applied to the line terminals; and a reset pin, wherein said latching mechanism includes a latching plate, and said initial reset prevention mechanism prevents said latching plate from engaging said reset pin when power is not applied to said line terminals.
