Higher level classes2#
Declared properties4#
ambient air temperature on which the time-current characteristics are based according to IEC 60898-1, 30°C being the preferred value
minimum value of current causing the circuit-breaker to operate automatically without intentional time-delay
availability of information on the variation of the tripping characteristic for ambient temperature differing from the reference calibration temperature
limit of the setting range of the AC current causing the operation of a release without any intentional time-delay
