Switch (circuit breaker) in the form of a box for low voltage, with a built in ammeter

摘要

A switch, in the form of a box, for low voltage, equipped with a front cover (5) which contains a data display unit or display (4) which indicates the value of the current which is flowing through the switch. The ammeter is electrically connected to an internal bus for communication with the protection module (6) of the switch (1), from which it receives a representative value for the current which is flowing through the switch. A control circuit (9) for the display and a logic circuit for the controller (8) are additionally provided, said logic circuit processing the information which is transmitted from the protection device. <IMAGE>
