| Zusammenfassung: | A miniature circuit breaker (2) includes separable contacts (14), an operating mechanism (10) structured to open and close the separable contacts, a microprocessor (6) including a thermal overload predictive function (17,18), and a shunt wire (8) in series with the separable contacts. The shunt wire is structured to measure current flowing through the separable contacts for the thermal overload predictive function (17,18) and an arc fault protective function. |
