Abstract: A plastic keypad with data entry elements and at least one display element is protected from electrostatic discharge by an assembly having an overlay substrate on which an electrically-conductive arrangement is disposed. The overlay substrate has a top side and a back side with a precisely-positioned vias formed through the substrate. A top surface of the top side is a layer of a conductive polymer. The back side is printed with at least one layer of color ink that depict a plurality of alpha-numerical and pictorial elements of the keypad. The electrically-conductive arrangement is disposed on the overlay substrate to collect electrostatic charges on the top side, transfer the electrostatic charges to the back side through the plurality of vias and drain the transferred electrostatic charges to a ground.

Abstract: A circuit breaker which includes a shielding component. The shielding component includes an external portion which defines a space external to the circuit breaker housing. The external portion prevents insertion of the circuit breaker into a breaker box closer than the distances defining the space. This can have the advantage of preventing arcing from the breaker contacts to the breaker box. The external portion may also prevent insertion of the circuit breaker into a breaker box such that a vent in the circuit breaker housing is blocked. In some implementations, the shielding component contains an internal portion which extends into the circuit breaker housing and is disposed to impede debris generated by contact arcing, or other debris, from entering the mechanism of the circuit breaker.

Abstract: Electrical equipment coupled to a printed circuit board provides insulation ribs projecting from a face between terminal plates provided on an upper face of the electrical equipment. The insulation ribs are inserted into oblong holes of the printed circuit board when the electrical equipment is coupled to the printed circuit board. As a result, insulation distances, namely creepage distance, between the terminal plates are along the height of the insulation ribs projecting from the upper face of the terminal plates.

Abstract: A gas-insulated electric apparatus includes: a sealed container made of metal; a high-voltage conductor, housed within the sealed container, that receives voltage; an insulating support member that insulates the high-voltage conductor from the sealed container and support the high-voltage conductor to the sealed container; and a nonlinear-resistance film covering at least a portion of an inner surface of the sealed container, the portion being on a lower side of the inner surface with respect to the high-voltage conductor. The nonlinear-resistance film is formed by particles of a nonlinear-resistance material and an insulating material, and the particles of the nonlinear-resistance material are dispersed in the insulating material. The particles of the nonlinear-resistance material are placed in the insulating material such that one or more of the particles of the nonlinear-resistance material is in constant contact with a conductive foreign object trapped inside the sealed container.

Abstract: A fixation system in use for medium or high voltage switching poles, insulators, circuit breakers, or general devices includes: an insulating housing provided with holes, in which screws are screwed into, in order to fix the device on a support, or a further housing. Inner surfaces of the holes are covered with a conductive layer or layers covering the inner surfaces at least partly. The conductive layers extend toward outside the holes. The conductive layers are conductively connected or connectable to ground potential.
