Electrical apparatus with a line side isolation safety switch

An electrical switching apparatus includes a first pole unit, a second pole unit, and a busbar assembly interconnecting the first pole unit with the second pole unit in series or in parallel. A first mechanism is configured to switch the first pole unit between its open and closed conditions. A second mechanism is configured to switch the second pole unit between its open and closed conditions. An actuating assembly is configured to actuate the first and second mechanisms to switch the first and second pole units from their open conditions to their closed conditions simultaneously, and to switch the first and second pole units from their closed conditions to their open conditions simultaneously.

A window assembly is for an enclosure. The enclosure has a plurality of walls. The window assembly includes a cover member structured to be coupled to each of the plurality of walls in order to form an enclosed region; a window member coupled to the cover member; a frame member coupled to the cover member; and a number of stud members each secured to the frame member and extending through the cover member. The cover member is located between the frame member and the window member.

Enclosure, and window assembly and assembling method therefor

A switch apparatus usable in a DC circuit employs a rotatable shaft having conductors that are removably connected with two or more pairs of contacts that are situated on line conductors and load conductors and that are connected in parallel by the conductors on the shaft. In rotating the shaft to open the switch, one pair of the contacts is electrically disconnected prior to electrical disconnection of the other pair of contacts. Further rotation of the shaft causes the other pair of contact to eventually become disconnected. Electrical arcs thus form only at the air gaps between the other pair of contacts and the conductor. Magnetic field elements in the form of permanent magnets are situated in the vicinity of the air gaps of only the other pair of contacts and apply Lorentz forces to the arcs to extinguish them.

Switch apparatus for connection with a DC circuit

An improved arc extinction apparatus that can be used in an improved DC switch apparatus includes a pair of magnetic field elements in the exemplary form of permanent magnets to apply Lorentz forces to the arcs. The magnetic fields are arranged in the vicinity of the air gaps that form between the ends of a pivoting conductor and a pair of contacts such that the system is optimized to extinguish an arc at one air gap when current is flowing through the conductor in a first direction and is further optimized to extinguish an arc at the other air gap when current is flowing in an opposite direction through the conductor. This is accomplished by providing a magnet at each air gap of the circuit, with the magnetic fields being oriented parallel with the pivot axis and having their north poles pointed in the same direction.

Arc extinction apparatus and DC switch apparatus

An enclosed switching apparatus includes an enclosure and a primary power supply disconnect mounted in the enclosure. The primary power supply disconnect has first and second terminals, the first terminals are electrically connectable to a primary power source and the second terminals are electrically connectable to a load. An auxiliary power supply unit includes an auxiliary power supply disconnect having third and fourth terminals. The third terminals are electrically connectable to the primary power source. A transformer has fifth and sixth terminals, the fifth terminals are electrically connected to the fourth terminals of the auxiliary power supply disconnect. An auxiliary fusible element has seventh and eighth terminals, the seventh terminal is electrically connected to one of the sixth terminals of the transformer. A receptacle has ninth terminals thereon. One of the ninth terminals is electrically connected to the eighth terminal of the auxiliary fusible element.

Safety switch with integrated auxiliary power supply and convenience receptacle

A locking assembly is for a circuit breaker including an enclosure and an operating handle operable between a first, ON position and a second, OFF position with respect to the enclosure. The operating handle includes a first aperture extending therethrough. The locking assembly includes a stationary element coupled to the enclosure and includes a second aperture extending therethrough. The second aperture corresponds with the first aperture of the operating handle when aligned therewith. A blocking element coupled to the operating handle blocks the second aperture when the operating handle is disposed in any position other than the second, OFF position in which the first aperture extending through the operating handle is aligned with the second aperture of the stationary element. A lock is inserted through the aligned apertures in order to lock the operating handle in the second, OFF position.

Operating handle locking assembly for an electrical switching apparatus

A safety switch with a spring toggle linkage which causes the switch shaft to rapidly rotate for opening and closing the switch has a lost motion coupling between the switch handle and the switch shaft which engages at about the point of toggling to assure positive operation of the switch.

Fail safe safety switch

A single piece fuse clip and switch blade contact receptacle is provided for use with an electrical switch, which may be a safety switch. The present invention provides an apparatus which eliminates the need for multiple connections, and which consolidates a switch blade receptacle portion with a fuse clip section in a single piece device employed in an electrical switching environment.

Combination fuse clip and line terminal connection device

A pair of slides (20,22) linearly reciprocally movable in opposite directions by a single operator handle (36) carry pins (24,26) which are received within dog-leg slots (14a,14b; 14a',14b') of levers (14,14') affixed to rotary operating mechanisms (6,6') of repsective ones of a pair of switches (4,4') for operating one switch to an ON condition while maintaining the other switch in its OFF condition in response to handle (36) movement in one direction, and for operating the switches to their reverse conditions in response to handle movement in an opposite direction, both switches being in their OFF condition in a center neutral position of the handle. Fuses (40,42) are connected to load side terminals of the switches and are connected together in common with the load to remove power from the fuses when the switches are OFF.
