Abstract: 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.

Abstract: A circuit interrupting device is provided. In some configurations, the circuit interrupting device includes a base and an arc chamber assembly received within the base. The arc chamber assembly includes an arc chamber framework and a plurality of splitter plates received within the arc chamber framework. The arc chamber framework includes a first plurality of protrusions and a second plurality of protrusions that laterally extend in a direction toward one another. Adjacent pairs of the first plurality of protrusions and the second plurality of protrusions are arranged on opposing sides of each of the plurality of splitter plates.

Abstract: A system comprising a magnetic actuator, a current transformer and operational electronics in a dual-coil circuit breaker. The system includes an inline, but non concentric, implementation of the primary and secondary coils to maintain a narrow width suitable for retrofitting in standard industrial rack mounted enclosures. The system further comprises an I-shaped lamination stack that is designed to abut on the ends of an upper and lower plate of the current transformer. The I-shaped lamination stack significantly increases the overlap between the lamination and the upper and lower plates, which results in lower magnetic reluctance and improves magnetic coupling.

The system includes an inline, but non concentric, implementation of the primary and secondary coils to maintain a narrow width suitable for retrofitting in standard industrial rack mounted enclosures. The system further comprises a split core design that is integrated into an upper and lower plate which slide together and are retained by a secondary coil bobbin. Typically, the two parts of the split core can be manufactured into net shapes by utilizing a powder metal or metal injection molding process. Moreover, the split core design disclosed herein can reduce costs and time associated with manufacturing and assembly of the current transformer.

Abstract: A terminal covering cap is mounted over the connection terminals of a multi-phase electrical switching device in order to increase the electric strength between the connection terminals of neighbouring phases. The L-shaped terminal covering cap closely abuts on its side facing the insulating housing the marginal region of connection openings leading to the connection terminals, with a negligible air gap. With this barrier, the required increased test voltage between the connection terminals can be withstood. On the side facing away from the insulating housing, the terminal covering cap is provided with ribs, to extend the creep distance on this side of the terminal covering cap. The terminal covering cap formed in this way makes it possible to carry out testing a the prescribed, increased test voltage without enlarging the insulating housing in order to extend the creep distance between the connection terminals of neighbouring phases.
