Differential circuit breaker associated with one or more circuit protection elements such as fuse units or circuit breakers

摘要

The differential switch includes a switch casing (1) having the same number of outputs (14,15,14a,15a) on opposing faces (1a,1b), separated from each other by a distance (a) corresponding to the spacing of the input terminals (4-7) of the protective elements (E,D). The inputs and outputs are thus joined by standard size U-link comb like connectors (P) on one side or the other of the casings (1,2,3). The switch (I) has the same number of inputs (12,13,12a,13a) on the two opposing faces. The protective elements (E,D) may include a fuse holder or circuit breaker. Both the switch and the protective elements are of the single pole and neutral type.
