Electrical device for supplying electrical power to electrical power units

An electrical device for supplying electrical power to multiple power units, comprising:

• a fixed support;
• input terminals for receiving a polyphase electric current;
• a first module comprising a first power line connected to the input terminals, said power line comprising an electrical circuit breaker;
• a second removable module comprising:
• second power lines connected to the first power line via an electrical distribution circuit configured to distribute the polyphase electric current from the first power line to each of the second power lines;
• a control circuit programmed to trip the circuit breaker depending on values of the electric current that is flowing through the second power lines;
• a connection interface provided with output connectors connected to the second power lines;
• removable elements each containing an item of electrical equipment intended to be connected to an electrical power unit via output terminals of said removable elements,
• each removable element being movable between an assembled position, in which each removable element is connected to the connection interface, and a removed position, in which each removable element is removed from the connection interface,
• the electrical equipment being connected to one of the second power lines via the output connectors of the connection interface when the removable element is in the assembled position,
• the control circuit being connected to a control interface of the electrical equipment of each removable element via a data link by virtue of the connection interface in order to send a control signal to said electrical equipment.
