ABSTRACT:
A protective device for an electrical installation, having at least two electrodes between which an electric arc can form, and a device for interrupting (6) the arc, extending between an upstream end (6A) and a downstream end (6B), with an entry region (E) for the arc at the upstream end (6A) thereof, at which point the arc enters the breaker device (6). The breaker device (6) has an insulation means (10) which permit the arc to enter the breaker device (6) while forming an obstacle to reaching the exit for the arc. The insulation means (10) are formed by one or more flexible ribbons which form a partial insulation barrier between the electrodes and the upstream end (6A). The invention further relates to overload and short-circuit protection devices.
