portion of the walls between the circuit breaker compartment and the bus-bar compartment, and between the circuit breaker
compartment and the cable compartment are made of insulating material. In the panel, for each phase: the circuit breaker unit (11)
comprises a first (111) and a second (112) connection contacts; a third connection contact (213) is positioned in the second
compartment (20) and is connected to a corresponding bus-bar; a fourth (314) and a fifth (315) connection contacts are positioned in
