Abstract
An electronic circuit interrupter digital display and keypad device includes a display to view circuit breaker settings combined with a keypad to select settings and values to be displayed. The display and keypad device connects to an electronic trip unit within the circuit interrupter by means of a tamper-free seal to prevent the circuit interrupter set points from being changed without authorization. Alternatively, a password-operated control switch provides a similar function.
