Arrangement of a busbar adapter with one or more electro-mechanical switching devices

A busbar adapter comprising:

• a housing being adapted to be attached to a busbar,
• a printed circuit board,
• at least one electric current sensor electrically connected with the printed circuit board, and
• electronics, and
• wherein the printed circuit board and the at least one electric current sensor are arranged inside the housing,
• wherein the housing comprises an upper housing part being adapted for the attachment of one or more devices to be connected through the busbar adapter to the busbar and a lower housing part being adapted for holding the printed circuit board and the at least one electric current sensor,
• wherein the lower housing part comprises a first part being adapted for holding the printed circuit board and the at least one electric current sensor and a second part being adapted to be attached to the busbar,
• wherein the electronics are configured to implement one or more energy metering related functions based on measurements made with the at least one electric current sensor, and
• wherein the energy metering function implemented by the electronics comprises generating power and energy data from the measurements made with the at least one electric current sensor and providing the power and energy data for further processing.
