Abstract
The output terminals (14P, 14N) of the phase and neutral supply circuits (12P, 12N) are on the same exterior surface (22) of the insulating case (11) as their input terminals (13P, 13N). Between the inputs and the insulating partition (15) is the cut-off section (18) which has a space (58) for an electromagnetic circuit breaker (59) with or without a thermal circuit breaker (60). A hole in the side wall (22) at right angles to the cut-off section allows access to the terminals. The transformer core (41) is part of a subassembly comprising an insulating body which is flush with the side face (22) of the case and which has a fork piece to hold output terminal on the primary turns.
