Abstract

1. A circuit-breaker for electrical installations comprising a casing (1) equipped with an input terminal (3) adapted to be connected directly to a first voltage (4) of the supply network, an output terminal (5) adapted to be connected to a second voltage (7) of the network, by means of a consumer circuit (6), a seating adapted to receive a fuse cartridge (8) in series with the input (3) and output (5) terminals and an indicator bulb (9), a normally open individual test contactor (12) being connected in series with this bulb (9), with a resistor (13) and possibly with a diode, between the output terminal (5) and the second voltage (7) of the network, the illumination of the bulb (9) being visible outside the casing (1) through a translucent wall element (17), characterised in that the bulb (9) is housed, with the resistor (13) and the optional diode, inside a support (16) of translucent material which is itself mostly housed inside the casing (1) of opaque material, emerging from this through a portion (17) constituting said wall element and which constituted the control member, which is movable against the action of a return spring (19), of the individual test contactor (12) of which it carries the movable contact (20), the fixed contact (23) of this test contactor (12) being carried by the casing (1).
