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.

A system including at least one sub-system that includes a first actuator configured to control a supply of a respective energy; a power lockout system including at least one switch configured to open and close an electrical connection between a power supply and the first actuator; a body configured to move between a first position and a second position to open and close the electrical connection; and at least one processor configured to control, during a power down process, the first actuator of the each of the at least one sub-system to reduce the respective energy of the sub-system.

Circuit breakers with a housing with a line side and a load side and an electronically controlled lock-out lock member coupled to the housing configured to electronically controllably travel between a first position and a second position. In the second position, the lock member is in a lock-out position and prevents the handle from moving to an ON position associated with electrical current conduction and in the first position the lock member is translated to a position that allows the handle to move to the ON position.

Hazardous location compliant solid state circuit protection devices include safety lockout components ensuring disconnection as a safeguard in the completion of power system maintenance and service tasks by responsible personnel. The safety lockout components may include a mechanical lockout interfacing with a physical lock element, an electrical lockout implemented through the controls of the solid state circuit breaker device, and combinations thereof. Visual device feedback and confirmation may be provided to personnel that the lockouts have been successfully activated, as well as successfully deactivated to reconnect and restore operation of the load side circuitry.

A handle of a manual operation mechanism of a circuit breaker, which includes an operating handle, a padlock device, and a locking shaft, wherein a middle of the padlock device is pivotally arranged on the operating handle, a front end of the padlock device is connected with the locking shaft, the padlock device is connected with the operating handle through a first driving member, a rear end of the padlock device is in limit fit with a locking mechanism, a padlock hole is arranged in the rear end of the padlock device, and the padlock hole is shielded by the operating handle.

A rotatable switching member includes a support bracket having a first arm, a second arm, and a middle portion, and a switch flange. The rotatable switching member further includes a switch bracket connected to the middle portion of the support bracket having an attachment portion and an engagement portion. A handle is fixed to the first arm of the support bracket to rotate the rotatable switching member.

The invention relates to a protective collar for at least partially receiving an actuating element which extends through a housing of a control unit and projects beyond an outer side of the housing. The protective collar has a base with a through-opening and a first circumferential collar radially spaced from the through-opening and extending from an upper surface of the base in a first direction. The first collar has at least two cut-outs such that the first collar forms at least two wings, wherein at least one of the wings has at least one predetermined breaking point extending in the circumferential direction.

A lockout system includes a hasp assembly and a plurality of tags. The hasp assembly has a back plate defining slots each sized and shaped to receive a tag. The back plate and tags each have openings that align when a tag is received in a slot. A first hasp portion has a first loop portion and a second hasp portion has a second loop portion. The first and second hasp portions are rotatable with respect to one another such that moving the lockout system has both an unlocked position and a locked position associated with an open position and a closed position. In the closed position, the first and second hasp portions complete and define a closed loop, where one or more tags can be installed in slots preventing further movement from the closed position.

Circuit breakers with a housing with a line side and a load side and an electronically controlled lock-out lock member coupled to the housing configured to electronically controllably travel between a first position and a second position. In the second position, the lock member is in a lock-out position and prevents the handle from moving to an ON position associated with electrical current conduction and in the first position the lock member is translated to a position that allows the handle to move to the ON position.

A circuit breaker is configured to ensure electrical safety when working on its circuits. The circuit breaker comprises a housing with an exterior boundary. The housing includes an “integrated” or “pre-installed” Lock-Off feature extending away from the exterior boundary. The Lock-Off feature having a hole that is configured to receive a shackle or a shank of a padlock. The circuit breaker further comprises a built-in Lock-Off mechanism including a handle integrated with the housing using a pivot such that the handle is configured to pivot relative to the hole in the Lock-Off feature. The built-in Lock-Off mechanism in combination with the Lock-Off feature is configured to prevent the handle from being turned ON with the use of the padlock. The padlock prevents the handle from rotating on its pivot such that the padlock disables the circuit breaker from turning ON by impeding the handle from rotating to an ON-position.
