发明名称 Circuit breaker with integrated ammeter
摘要 An integrated circuit breaker and ammeter device includes a generally conventional electrical circuit breaker with an enclosing case and a primary current carrying conductor running through the case, and an ammeter circuit mounted with the case and operatively connected to the primary conductor so as to read and display the value of the current flowing through the primary conductor of the circuit breaker. In the preferred embodiment the primary conductor functions as the primary winding of a transformer and the ammeter circuit is directly connected to the secondary transformer winding. The ammeter circuit preferably further includes a display panel mounted on the case in a readily visible location.
