Abstract
An electrical power circuit breaker includes an electric overcurrent trip unit for processing a signal from a current sensor. A flexible connecting line is provided for connecting the current sensor to the overcurrent trip unit and a first component of a two-part plug apparatus is fitted to its end. The second component of this plug apparatus is part of the overcurrent trip unit. At least one resistor is arranged between contact pins in the first component, in order to code individual characteristic values or combinations of such characteristic values, such as the rated current or switching rating class.
Claims10
An electrical power circuit breaker, comprising:
- an electromechanical assembly including at least one switching contact, a drive apparatus which operates the switching contact, and at least one latching devices for allowing energy stores to close and open the switching contact;
- a current sensor for detecting a current flowing via the switching contact;
- an electronic overcurrent trip unit for processing a signal from the current sensor and for emitting a signal instructing the at least one latching device to open the switching contact;
- a moving connecting line for connecting the current sensor to the overcurrent trip unit;
- and
- an information memory for passing characteristic values of the electromechanical assembly in the power circuit breaker to the overcurrent trip unit, wherein
- the information memory is a part of a first component, which is connected on the connecting line of a two-part plug and socket apparatus, whose second component is part of the overcurrent trip unit.
