Abstract: A pushbutton resettable circuit breaker is shown having features to prevent manual opening by simply pulling outwardly on the pushbutton. In one embodiment, the pushbutton (16) is formed with slots (16b) which are configured to provide a reaction surface essentially inaccessible without a special purpose contact opening tool (30). The tool is provided with portions that are insertable into the slots and into engagement with the reaction surfaces for pulling the pushbutton out and manually opening the contacts. In a second embodiment, a small aperture 16k is formed through the rating tab and top and wall of the button and in alignment with a movable plunger (28). A special purpose contact opening tool (32, 34) can be inserted through the aperture to apply a force to the plunger and mechanically trip the circuit breaker.

Abstract: A method for providing a cost quote for a complex model data analysis is provided, wherein the analysis is performed on a computer device remotely disposed with respect to a computer terminal adapted to be used by a user. First, the user at the remote computer terminal is prompted to select an input data and an analysis parameter for an analysis of the data input according to a complex model. An automated cost calculator function is then executed in response to the selected input data and analysis parameter, wherein the cost calculator function is particularly configured with respect to the complex model so as to provide a cost quote for execution of the corresponding analysis by the computer device. The cost quote is thereafter provided to the user at the remote computer terminal.
