MODULAR APPARATUS WITH RETRACTABLE CONNECTION PIONEER AND SELF-PROTECTED ELECTRICAL ASSEMBLY COMPRISING SUCH A MODULAR APPARATUS CONNECTED TO A CIRCUIT BREAKER

摘要

The invention relates to a modular apparatus (300) comprising a housing (310) provided with two parallel main lateral faces (313) parallel to one of which is adapted to be joined to another modular apparatus, the housing housing transfer elements state and a pin (133) linked to one of these elements (131). According to the invention, said pin is adapted to be displaced in translation along an axis (X) perpendicular to one of the main lateral faces between a retracted position in which said pin is placed inside the housing set back from said lateral main face. and an extended position in which said pin passes through an opening in said side main face to extend outside said housing projecting from said side main face. The invention also relates to a self-protected electrical assembly comprising a protective device as mentioned above and a circuit breaker assembled with one another by one of their main lateral faces.
