ELECTRICAL APPARATUS,PARTICULARLY A RELAY OR A SMALL-SIZE CONTACTOR

摘要

An electrical apparatus which can be dismantled and is adapted to be fitted onto a fixed standard-shaped rail or section. The apparatus comprises a prism-shaped casing (50) having a rectangular opening (60) into which is accommodated a removable bottom (5) on the sides of which are provided means (25, 27) for fastening it to said casing and outer hooks (19, 20) adapted to cooperate with said shaped rail (2). Such an apparatus is particularly advantageous when its dimensions approximate the transverse dimensions of the rail or section, as it is the case when a small-size contactor or a relay is to be fitted into the casing.
