Abstract
Abstract An electrical connection and protection device suitable for conventional wall installation, which device includes circuit breaker features, is provided with a housing box for accommodating a circuit breaker as well as ground fault sensing means. The housing box allows for a compact arrangement in which all such functions can be combined in a nearly conventional wall receptacle arrangement.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
113 words
An electrical connection and protection device for use with an electrical socket, comprising a housing box, a switching mechanism in the housing box for disconnecting power to the housing box, said switching mechanism having a control element and testing means; said housing box enclosing a double contact point for making and breaking connections, a disconnect magnet coupled to the double contact point and having a fixed core and a moving armature, electronic circuit means responsive to external currents and coupled to said windings for energizing at least one of the windings in response to the currents; a socket having a connector jack, a cover for holding said connector jack and covering the housing.
Claim 2
Dependent Claim
113 words
An electrical connection and protection device for use with an electrical socket, comprising a housing box, a switching mechanism in the housing box for disconnecting power to the housing box, said switching mechanism having a control element and testing means; said housing box enclosing a double contact point for making and breaking connections, a disconnect magnet coupled to the double contact point and having a fixed core and a moving armature, electronic circuit means responsive to external currents and coupled to said windings for energizing at least one of the windings in response to the currents; a socket having a connector jack, a cover for holding said connector jack and covering the housing.
Claim 3
Dependent Claim
74 words
An electrical connection and protection device according to claim 1, wherein said housing box has the form of a parallelepiped, the connector receptacles and the electronic switching means held by said cover are superposed on one narrow end thereof, while the switching mechanism and the release magnet are arranged in the space adjoining another narrow end thereof, and two arcing chambers associated with the double contact point are arranged next to the release magnet.
Claim 4
Dependent Claim
46 words
An electrical connection and protection device according to claim 1 wherein said release magnet mechanism includes contact studs, said armature being coupled mechanically with the moving contact studs so that an accelerating opening force is exerted directly on the contact studs when the armature is released.
Claim 5
Dependent Claim
47 words
An electrical connection and protection device according to claim 1 wherein one winding of the release magnet comprises an insulated flat band whose width corresponds to the entire length of the release magnet and which forms the carrier for the second winding of said pair of windings.
Claim 6
Dependent Claim
39 words
An electrical connection and protection device according to claim 3 wherein said release magnet mechanism includes a spring for fixing the armature being arranged inside the release magnet between the fixed core and the moving armature of the magNet.
Claim 7
Dependent Claim
60 words
An electrical connection and protection device according to claim 1 comprising a wall box with fastening flanges and having a greater depth than the housing box, the housing box being inserted into said wall box and a cavity for receiving terminals and feed wires is formed between the bottom of the wall box and the bottom of the housing box.
Claim 8
Dependent Claim
85 words
In an electrical connection and protection device having a conventional wall electrical housing box and receptacle means for receiving a conventional plug, the improvement comprising that said housing box is compartmentalized and includes a circuit breaker for disconnecting electrical power to said receptacle means, a switching mechanism for operating said circuit breaker, and an electronic switching means responsive to a change in current level indicating a fault for disconnecting a voltage from said switching mechanism so as to change the condition of the circuit breaker.
Claim 9
Dependent Claim
85 words
In an electrical connection and protection device having a conventional wall electrical housing box and receptacle means for receiving a conventional plug, the improvement comprising that said housing box is compartmentalized and includes a circuit breaker for disconnecting electrical power to said receptacle means, a switching mechanism for operating said circuit breaker, and an electronic switching means responsive to a change in current level indicating a fault for disconnecting a voltage from said switching mechanism so as to change the condition of the circuit breaker.
Claim 10
Dependent Claim
46 words
The device of claim 7, wherein said switching mechanism includes a control element and testing means, contact means coupled to said receptacle means for making and breaking connections, and a disconnect magnet coupled to the contact means and having a fixed core and a moving armature.
Claim 11
Dependent Claim
25 words
The device of claim 7, wherein said switching mechanism comprises arc suppression means, said arc suppression means being physically remote from said electronic switching means.
