Abstract

A low-voltage circuit breaker includes an enclosure. The enclosure includes a front wall and a rear wall, and further includes specific functional subdivisions. The front wall and the rear wall are separated from one another by a separating joint, which runs vertically in the in-use position, between the enclosure front wall and the enclosure rear wall. An integrated cable duct is provided in the base of the enclose rear wall. The cable duct can be covered and extends underneath the contact support bearings and underneath the current transformer chambers which surround the lower connecting rails essentially over the entire width of the low-voltage circuit breaker. In the direction of the enclosure front wall, it has one or more through-opening for the connecting cables to pass through between the current transformers and the electronic tipping unit.
