Abstract
Abstract A low voltage circuit breaker having a housing of insulating material separated into an upper part and a lower part. A slot is provided one side wall of the lower part beginning at the parting line and extending to the lower edge of the lower part in which wires leading to an auxiliary device can be installed. An outlet is provided at the separation for these wires. The slot makes it possible to arrange several identical low voltage circuit breakers with connected auxiliary wires directly next to each other.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
123 words
In a low voltage circuit breaker comprising a housing of insulating material consisting of an upper part and a lower part and at least one auxiliary device arranged within the housing which can be connected by wires to switching apparatus located outside the housing, the improvement comprising: at least one sidewall of the lower part of the housing having a slot for receiving the wires so that they do not project beyond the side contour of the housing, the slot starting at the parting of the housing and extending to the lower edge of the lower part; and an outlet in a wall of the housing at the parting for passage of wires from the slot to be connected to the auxiliary device.
Claim 2
Dependent Claim
123 words
In a low voltage circuit breaker comprising a housing of insulating material consisting of an upper part and a lower part and at least one auxiliary device arranged within the housing which can be connected by wires to switching apparatus located outside the housing, the improvement comprising: at least one sidewall of the lower part of the housing having a slot for receiving the wires so that they do not project beyond the side contour of the housing, the slot starting at the parting of the housing and extending to the lower edge of the lower part; and an outlet in a wall of the housing at the parting for passage of wires from the slot to be connected to the auxiliary device.
