Abstract
A removable keypad controls the electronic trip unit used within state-of-art electronic circuit breakers. The keypad allows inputting and displaying relevant circuit interruption information. Unauthorized access to the trip unit settings is prevented by blocking off the keypad 'ENTER' key while still allowing access to the keypad's remaining function keys.
