Abstract:
    The invention relates to an overvoltage protection device (1) embodied to provide protection in common or differential modes and comprising at least one electrically-insulated housing (2), specifically embodied to house at least one electrical binomial, formed by a so-called ground-phase varistor (PT), with a phase connector (p) and a ground connector (t), arranged between a first phase (L1) for protection and ground (T) and a so-called neutral-phase varistor (PN), with a phase connector (p) and a neutral connector (n), arranged between said first phase (L1) for protection and neutral (N), said phase-ground (PT) and phase-neutral (PN) varistors being mounted next to each other within said housing (2) such as to form an assembly binomial (3), characterised in that the protection device (1) comprises electrical insulation means (20), embodied for the electrical insulation of the ground connection (t) from the phase-ground varistor (PT) and the neutral connection (n) from the phase-neutral varistor (PN). The invention relates to devices for protection against overvoltages.
