This rotary control system for a device includes a rotary control member, rotationally mobile about a first fixed axis, between first and second positions, and a rotary control handle, intended to be secured in rotation with the rotary member about the first axis. It also includes a blocking device, that can be selectively moved, when the rotary member is in its first position, between a blocking configuration, in which it prevents the movement of the rotary member to its second position, and a release configuration, wherein the movement of the rotary member to its second position. This system further includes a locking plate, rotationally mobile about the first axis relative to the rotary member, when the rotary member is in its first position, between a locking position, in which a first orifice passing through the rotary member is superposed with a second orifice passing through the locking plate.

An engageable drive engageable operating mechanism for converting a movement of a linear translation operating handle to a rotating handle movement relative to the operative front face engageable with a molded-case circuit breaker. The mechanism includes an external rotating adapter external rotating operating member or alternatively an engageable drive engageable operating mechanism incorporating a handle assembly external rotating operating member, interchangeable with each other; and a gear, a support movable movement-converting support including a rack portion, and a structural support base, wherein the structural support base includes a built-in side opening chamber.

A rotary motion switching apparatus is usable with a circuit interrupter that is situated in a NEMA box or other box and employs an attachment system. An access port that is formed in a wall of the NEMA box or other box permits a shaft having a handle at an end thereof to be connected with the rotary motion switching apparatus. The rotary motion switching apparatus includes a universal joint on a rotational component that enables operation of the handle and shaft without binding on the wall of the NEMA or other box even if the access port in the box is offset from an axis of rotation of the rotational component.

A rotary motion switching apparatus is usable with a circuit interrupter and employs an attachment system having a pair of connectors that are received in a pair of openings formed in a housing of a circuit interrupter and that are affixed to the housing within the openings in order to resist removal of the rotary motion switching apparatus from the circuit interrupter. The openings are pre-existing in the housing of the circuit interrupter and are provided to enable access by tools with terminals of the circuit interrupter to which load wires and the like are connectable. The connectors thus secure the rotary motion switching apparatus to the circuit interrupter by using openings that are already formed in the circuit interrupter and thus the rotary motion switching apparatus is usable without requiring a modification to the housing or to the molds that are employed to form the housing.

An electronic switching device includes a housing with at least one housing door, a lockable rotary handle rotatable at least between an ON position and an OFF position, a handle locking device for locking the rotary handle at least in the OFF position when engaged, and a POFF device for preventing the rotary handle to be rotated and/or fixed in OFF position when activated. The electronic switching device further includes a locking coulisse, movably arranged at the electronic switching device and arrangeable in at least a first position, a second position and a third positions with respect to the housing of the electronic switching device. The locking coulisse is configured for allowing an engagement of the handle locking device and the POFF device in the first position, locking the housing door in the second position and blocking the activation of the handle locking device in the third position.

A switching operation mechanism to a molded case circuit breaker, including at least one operating handle, which is movable in a rotatable trajectory, said switching operation mechanism including at least one external rotary handle, at least one operation member and at least one movement transmission means, the said operation member being capable of moving in rotating trajectory in equivalent direction to the movement in rotating trajectory of the handle for operating the circuit breaker in molded case, arranged inside a housing including a laterally bipartite body, reaching an efficient movement transfer, requiring less mechanical effort of proportional operation of the user on the external rotary handle, wherein it is possible to maintain an external rotary handle, of great dimensions proportional to the assembled assembly, within the general perimeter of the molded case circuit breaker.

An actuator assembly for actuating electrical switches housed in an electrical enclosure is disclosed. The assembly includes at least one handle assembly including a handle positioned above a cover of the enclosure, a trip bracket positioned below the cover and a shaft connecting the handle to the trip bracket. At least one slider actuator is slidably mounted over the electrical switch and coupled to a toggle of the electrical switch. The slider actuator has a drive link which is adapted to be engaged with the trip bracket such that rotation of the handle causes the drive link to slide which in turn causes a linear movement of the slider actuator to toggle the electrical switch. The use of the slider actuator allows a higher density of electrical switches to be stacked inside the enclosure.

An operating mechanism for a toggle switch handle includes a bar that is movably mounted along its longitudinal axis, and a roller head mounted at one end of the bar. The roller head includes two axes for rolls. The first roll of the rolls is provided for turning on the toggle switch handle depending on a movement of the bar, and a second roll of the rolls is provided for rolling over a plate and blocking a rotation of the bar around its longitudinal axis.

A breaker actuator includes a slide plate, at least one actuator lever, and a drive plate. The slide plate is linearly movable. The actuator lever is rotatable about a pivot. The actuator lever engages the slide plate and rotational movement of the actuator lever is actuatable by linear movement of the slide plate. The drive plate is moveable between an off position and an on position and is actuatable by rotational motion of the at least one actuator lever. A method for actuating a breaker includes moving a slide plate linearly from a first position to a second position, rotating at least one actuator lever about a pivot from a first position to a second position by the linear movement of the slide plate, and moving a drive plate in front of an electrical breaker from an off position to an on position by the rotational motion of the actuator lever.

A lockout, tagout (LOTO) device and associated implementation method for a switchable energy isolation device are provided. The isolation device includes first and second electrical terminal members and a slideable linkage disposed and in electrical communication therebetween for switching the electrical terminal members between isolated and non-isolated states. The LOTO device includes a cover member configured to extend over the terminal members and the linkage, and a fastener member coupled to the cover member. The fastener member is configured to engage the first or second electrical terminal member to secure the cover member to the isolation device. A tagging member is configured to engage the fastener member and a securing member engaged with the cover member, upon the cover member being secured to the isolation device, to prevent the fastener member from disengaging the first or second electrical terminal member without the tagging member disengaging the fastener member.
