1. A circuit breaker for a low-voltage circuit having input connections and output connections for conductors of the low-voltage circuit, the circuit breaker comprising:
a current sensor for determining a level of an electric current in the low-voltage circuit, said current sensor being connected to an electronic trip unit that has a display for displaying information and that is configured to interrupt the low-voltage circuit if current limit values or current/time limit values are exceeded;
said display of said electronic trip unit being a removable display;
said display having a sensor for determining an inclination or an angle of a horizontal or vertical position of said display, and being configured such that a content of displayed information is adjusted depending on a horizontal or vertical mounting of said display, thus enabling the displayed information to be read in a user-friendly manner; and
said display having a display microcontroller, connected to said sensor, for controlling a display of the displayed information.
