Abstract

A device with differential protection comprises a case (203) including two main panels (204, 302) and first side panel (205, 303), whereon output terminals (209, 210, 311, 312) are located, a circuit breaker (211) comprising a compartment (235) having a wall (241, 331) wherein at least first through hole (242, 243, 332, 333) is provided, a differential protection unit (212) separated from the circuit breaker (211) by a partition (213; 351), which is parallel to main panels, connecting conductors (244, 245, 335, 336, 337, 338) pass through at least one through hole, connecting conductors pass through at least one second through hole (251) performed in the partition.
