<p>In the case of an electrical service arrangement having at least one switching device (3), at least one measurement/evaluation unit (2) and at least one display/control unit (1), with the switching device (3) having switching contacts (31), a switching mechanism (32) and a tripping unit (33), with the measurement/evaluation unit (2) having at least one sensor (21) for measuring a physical variable, with the display/control unit (1) having display means (12) and/or a data processing unit (11), and with the at least one switching device (3), the at least one measurement/evaluation unit (2) and the at least one display/control unit (1) each having a first interface (6) for interchanging data between them, and with the display/control unit (1) having a second interface (7) which is in the form of an active radio interface, for interchanging data with a user terminal (4), it is proposed in order to increase the safety, security and reliability with less hardware and installation complexity, that the first interfaces (6) be in the form of active radio interfaces.</p> |
