The invention relates to a switching device including a housing having a front housing and a rear housing. The rear housing includes a rear housing face, and a first sidewall, first end a second sidewall, and a second end wall projecting from the rear housing face to form at least one interior chamber. The sidewalls of the rear housing include a rear housing tab that projects away from the rear housing face. The switching device further includes a splitter plate support, comprising first and second support panels, located within the interior chamber. The first support panel further includes a support hook that extends from the outer panel face. The support hook has an aperture that engages the rear housing tab, in which the rear housing tab extends through the aperture of the support hook, forming a double-walled panel and reinforcing the housing.

A circuit breaker with improved trip unit fixation is disclosed. Another circuit breaker and a system also perform the functions of the circuit breaker. A circuit breaker includes a frame and a trip unit mounted in the frame. The trip unit includes a terminal for securing a wire to the trip unit. One of a wall of the frame and the trip unit include a protrusion and the wall of the frame or the trip unit without the protrusion includes an opening. The protrusion conforms to the opening and the protrusion and opening are positioned to oppose movement of the trip unit in a direction of a force resulting from securing the wire in the terminal.

A circuit breaker comprises a body made of a nanocomposite material formed by insertion of nano particles of a nano particles material in thermoplastic polymer of a thermoplastic polymer material. A method of reinforcing a material with another material, the method comprises mixing homogenously a thermoplastic polymer material with a nano particles material in a hot process to reinforce the thermoplastic polymer material with the nano particles material and forming a nanocomposite material by insertion of nano particles of the nano particles material in thermoplastic polymer of the thermoplastic polymer material. The nano particles material has a mechanical wear property, a dielectric property and a thermal property of fire retardant.

A harness assembly includes a plurality of individual wires and a restriction mechanism. The restriction mechanism has a sleeve member surrounding each of the plurality of individual wires in order to prevent longitudinal movement of each of the plurality of individual wires with respect to each other. Each of the plurality of individual wires has a helical-shaped portion located internal with respect to the sleeve member, thereby allowing each of the plurality of individual wires to engage the sleeve member.

A switchgear for an electric current includes a switching assembly that can be switched between an open state and a closed state; a control mechanism including a trigger member for triggering the switching of the switching assembly to the open state; a housing including lateral walls. The lateral walls are elastically deformable when the pressure prevailing inside the housing increases, one of the lateral walls including, on its inner face, a rigid protuberance, the deformation of the wall causing a displacement of the protuberance, the protuberance being arranged relative to the trigger member such that its displacement results in the displacement of the trigger member to its triggering position.

Flame resistant compositions based on nylon-6 (PA 6) or nylon-6,6 (PA 66) may include melamine cyanurate, titanium dioxide, glass fibers, and non-fibrous and non-foamed ground glass having a specific particle size distribution, geometry and optionally sizing. Methods for producing the composition are also provided, as well as use of the compositions for production of products for the electrical industry, preferably electrical components such as residual current circuit breakers and other circuit breakers.

A circuit breaker housing assembly is disclosed. The housing (47) includes a first housing piece (14) defining a first interior surface (52) including a first mating surface (152), and a second housing piece (60) defining a second interior surface (62) including a second mating surface (260) which is opposingly coupled to the first mating surface to define a seam (202) therebetween. An adhesive material (201) is disposed between the corresponding first and second mating surfaces along the seam. A moveable contact is disposed in the housing and is selectively moveable with respect to a corresponding stationary contact. The first and second interior surfaces (52,62) further cooperatively define a first recess (120) therebetween, and the moveable contact assembly is disposed in said first recess.
