摘要： An emergency stop button actuated by pushing and unlocked by rotation. A lug 16 provided on the skirt 12 of the head 11 of the button works with a sliding plate 20 which can block the head when it is pulled and put into the interlocked position. The sliding plate has, for this purpose, an abutment face 25 for the lug and a window 24 to allow the lug to pass when it is rotated in order to unlock the emergency stop button.

摘要： A protective cover for use on a device having a switch. The protective cover prevents inadvertent or accidental operation of the switch, while allowing deliberate or intentional operation of the switch with the protective cover in place. The protective cover includes a plate and a pair of access apertures defined by the plate. One of the pair of access apertures is positioned to enable operation of the switch from a first position to a second position, and the other of the pair of access apertures is positioned to enable operation of the switch from the second position to the first position. The area of each access aperture is of suitable size to prevent inadvertent operation of the switch. The plate is attached to the device using attaching means that allows the plate to be attached to the device in only one orientation.

摘要： This invention relates to a high ampere-rated circuit breaker which meets the electrical code requirements of the world market. The circuit breaker electronic trip unit is contained within a recess in the circuit breaker cover and is interlocked with the circuit breaker operating mechanism to articulate the operating mechanism upon removal. A padlock assembly arranged within the circuit breaker case prevents the circuit breaker contacts from being closed and the cover from being removed. The padlock assembly is only functional when the circuit breaker contacts are in the OPEN condition.

摘要： A guard for preventing movement of a handle by an operator from a locked position to a second position. The handle is coupled to an operating mechanism which controls a distribution device. The handle extends outwardly from the surface of the distribution device. The guard includes a cover which is configured to substantially enclose the handle while in the locked position. The cover is supported about the handle by abutting the surface of the distribution device. The cover is also configured to allow the handle to move from the locked position to the second position wherein the cover prevents an operator, but not the operating mechanism, from moving the handle from the locked position to the second position and the handle positively indicates the state of the operating mechanism between the positions. The guard also locks the cover to the distribution device. The present invention also a method of positively indicating the state of an operating mechanism controlling a distribution device while simultaneously preventing movement of a handle coupled to the operating mechanism by an operator from a locked position to a second position. The handle is coupled to an operating mechanism which controls a distribution device. The handle extends outwardly from the surface of the distribution device.

摘要： An electric switch assembly having a switch arm movable from "on" to "off" position and a cover plate through which the switch arm extends. The cover plate has an integral guard providing a stop substantially abutting the switch arm when in one of its "on" and "off" positions and blocking movement of the switch arm to the other position. The cover plate may replace the conventional cover plate or serve as an auxiliary cover plate applied over the conventional cover plate.

摘要： A motor operator unit for an electrical switch is pivotally mounted on a bracket to swing between a closed, operative position in which an actuator in the motor operator unit engages the switch handle for electrical operation of the switch handle and an open position in which the switch handle is freely accessible for direct manual operation. The compliant actuator which is translated by a motor driven threaded shaft overtravels at each end of its reciprocal path after actuation of the switch handle to toggle a single power switch which determines both direction and shutoff of motor operation. A lockout plate mechanically prevents electrical and manual operation of the switch handle and carries an interlock switch which only enables motor operation when the motor operator unit is in the operative position and not locked out. The actuator is configured to prevent full rotation of the motor operator to the operative position, if the position of the actuator, which is virtually identified by indicators, does not correspond to handle position.

摘要： The invention relates to a device for both mechanical and electrical lockout of a remote control unit for a modular circuit breaker. This device includes a retractable ring pivoting around a spindle and provided with a locking nose arranged to cooperate with a stop pin located on the circumference of a drum rotating around a spindle and bearing a manual control handle having two stable positions. The retractable ring bears in addition a rocker designed to actuate a switch fitted on the electrical supply circuit of the remote control unit. This device is advantageous in that it also enables padlocking or sealing of the retractable ring.

摘要： A circuit breaker equipped with an add-on remote control unit comprises a mechanical transmission link independent from the main mechanism, to transmit the position of the movable contact to an indicator, which automatically unlocks a latch in the open position to enable padlocking of a rack. The mechanical link is in two parts, composed of a push-rod associated with an operating lever on which the indicator is arranged, and a link rod articulated on the switching bar.

摘要： A safety lockout apparatus for an electrical circuit includes an electrical switch, a key, a lock and a blocking mechanism. The electrical switch is movable between an ON position at which the electrical circuit is energized and an OFF position at which the electrical circuit is deactivated. The lock is adapted to receive the key and is rotatable among a plurality of positions by the key. The key is only insertable and removable when the lock is at a preselected position. The lock is maintained in the preselected position when the key is removed from the lock. The blocking mechanism physically maintains the switch in its OFF position when the key is removed from the lock.The blocking mechanism preferably includes a member driven by the lock between a first position at which the electrical switch is movable between its ON and OFF positions and a second position at which the member physically maintains the electrical switch in its OFF position. Advantageously, the driven member's second position corresponds to the preselected position at which the key can be removed from and inserted into the lock.
摘要翻译：用于电路的安全锁定装置包括电开关，钥匙，锁和阻塞机构。电开关可以在电路通电的ON位置和电路停用的OFF位置之间移动。该锁适于接收钥匙，并可通过钥匙在多个位置之间旋转。当锁处于预选位置时，钥匙只能插入和拆卸。当钥匙从锁中取出时，锁将保持在预选位置。当钥匙从锁中取出时，阻挡机构将开关物理地保持在OFF位置。阻塞机构优选地包括通过锁定在第一位置和第二位置之间的构件，第一位置和第二位置之间，在该第二位置，电开关可以在该第一位置和第二位置之间移动。有利地，从动构件的第二位置对应于可以从钥匙被移除并插入锁中的预选位置。
