A switch unit, preferably implementing a circuit breaker, includes a contact slide unit formed by a contact slide, a fixed contact piece and a moveable contact piece), and a short-circuit release that acts to displace the moveable contact piece by means of a tappet in the event of a short-circuit. A moveable braking device is configured and arranged such that, following circuit opening displacement of the moveable contact piece in response to a short-circuit, the moveable brake device dampens the return, rebound movement of the moveable contact piece to reclose the circuit.

Switch unit, in particular a circuit breaker

A switching device is disclosed, in particular a circuit breaker, with a thermal release, on which a moving switching piece is arranged by a contact link support. The moving switching piece is borne on a spring body and is arranged opposite stationary switching pieces. A heat-extraction apparatus composed of a heat-dissipating material is in each case arranged at the side, along the stationary switching pieces.

Switching device with a heat extraction apparatus

A circuit breaker includes a housing equipped with a first switchgear region, in which a quenching chamber device and a sliding contact device having movable contacts are located, the contacts lying opposite fixed contacts, and equipped with a second switchgear region, in which a current release assembly consisting of a short-circuit release and an overload release are located. In an embodiment, a continuous ventilation channel is formed within opposing housing walls along the fixed contacts, the channel acting as a first convective air-flow through the circuit breaker in order to dissipate the heat.

Circuit breaker comprising ventilation channels for efficient heat dissipation

To improve manufacture of an electronic circuit, the electronic circuit is composed of modules of sub-circuits arranged on a common substrate, such as a cooling body, and that are electrically interconnected by a planar electrical contact element.

Electronic circuit composed of sub-circuits and method for producing

A power semiconductor module is disclosed including a housing for receiving at least one essentially board-type circuit carrier, the circuit carrier being provided with a metallization on at least one part of its surface and being populated with and electrically connected to at least one power semiconductor, rigid, integral and essentially straight load connection elements being applied on the metallized part of the metallized surface of the circuit carrier, which load connection elements are electrically and mechanically fixedly connected to the circuit carrier by one of their ends and project essentially perpendicularly into the housing interior, separate connection terminal elements for electrical conduct-making being placed onto the free end of the load connection elements.

Power semiconductor module comprising load connection elements applied to circuit carriers

A device for contacting an electric line includes a contact element, which has at least two contact tongues on the side facing the line. To achieve secure contacting, the contact element includes clamping halves, which are arranged resiliently in relation to one another.

Device for contacting an electric line, especially a flat conductor cable

To dissipate heat from a lossy electronic component which is fixed to the inner side of a wall of a housing, several of the outer and/or inner sides of the housing are placed into contact with a cooling element. In this way, a large part or all of the housing surface can be used to dissipate lost heat to the surroundings.
