Abstract: A method and tool for an integrated power switching device configuration tool and fault response tolerance calculator determines the fault response tolerance characteristics of a power switching device, adjusts the predicted fault responses based on the fault response tolerances and displays the adjusted fault response results. The fault response tolerance calculation tool uses configuration information defined during the configuring of the power switching device and applies this information to an overcurrent response curve selected by a user. The tool calculates the different fault response tolerances and adjusts predicted response times accordingly. The adjusted fault responses are displayed to the user along with a range of recommended fault response values.

Abstract: An electromagnetic actuator is provided that comprises a housing, a solenoid coil, and an armature. The armature is movably disposed in an interior cavity defined by the housing. Irregular gaps are formed between the armature and the housing to increase the initial force of the actuator and to improve the latching force of the actuator after the actuator has been actuated.
