Abstract

The invention relates to a circuit breaker for a low-voltage circuit having input and output terminals for conductors of the low-voltage circuit. Within the circuit breaker, the low-voltage circuit can be interrupted or closed. The circuit breaker also has a current sensor which determines the level of the electrical current in the low-voltage circuit and is connected to an electronic trigger unit which has a display for displaying information and interrupts the low-voltage circuit if current limit values or current-time limit values are exceeded. The display is designed to be removable.
