Each of the electrical contacts is structured to be electrically connected to the electrical switching apparatus.
Waterproof cover for a resettable in-line fuse
A waterproof cover for a resettable in-line fuse having a cover with a top end and a bottom end; a seal mount on the top end; and a flexible seal for the seal mount. The seal mount has a hollow interior and an annular flange. The flexible seal has a top portion, a middle portion, and bottom portion. A translucent flexible dome is positioned on the top portion and an internal annular groove is positioned in the middle portion to engage the annular flange. A seal is positioned in the bottom end of the cover and positioned around a female section of the resettable in-line fuse. A seal is also positioned in a bottom end of the female section of the resettable in-line fuse to produce a waterproof fuse. A reset button is visible in the translucent flexible dome when the resettable in-line fuse is tripped. The fuse can be reset by pushing the flexible dome against the reset button.
Medium voltage circuit breaker in subsea environment
A medium voltage circuit breaker in a high pressure subsea environment includes: a vacuum circuit breaker; and a drive in a pressure tight housing. For an electrical three-phase arrangement, one vacuum circuit breaker per phase is arranged in a separate pole housing each, and the resulting three pole housings are mounted to a common base compartment, in which three drives for the three vacuum circuit breakers are arranged. The three pole housings and the common base compartment are attached such that they commonly form a pressure tight compartment.
MOLDED CASE CIRCUIT INTERRUPTER HAVING CIRCUITRY COMPONENT SITUATED ADJACENT REAR EXTERIOR SURFACE
A molded case circuit interrupter advantageously employs a circuitry component that is situated adjacent a rear exterior surface of the molded case of the molded case circuit interrupter. Previous circuit interrupters have sometimes employed a non-conductive backsheet of a nominal thickness of 0.062 inches that was adhered to the rear surface of the molded case circuit interrupter in order to electrically isolate screws, posts, and the like that were mounted to and that were exposed on the rear portion of a molded case thereof. The disclosed and claimed concept provides a circuitry component in place of or in addition to the back sheet, with the circuitry component including flexible ribbons having electrical conductors that extend through holes formed in the molded case and that are electrically connected with electronic components that are situated within the interior of the molded case.
Surge protector and base therof
A base of a surge protector, the surge protector comprising a function rotating member (3), and the function rotating member (3) having a remote linkage rod contact wall (3D) and a remote linkage notching (3H), and the base comprising a remote device, and the remote device having at least one remote linkage rod (9), and when the function rotating member (3) is situated at the first position, the remote linkage rod (9) is pressed down by the remote linkage rod contact wall (3D), and when the function rotating member (3) is rotated from the first position to the second position, the function rotating member (3) is rotated from the remote linkage rod contact wall (3D) to the remote linkage notching (3H) with respect to the point of action of the remote linkage rod (9) to release the remote linkage rod (9).
Circuit Breaker With Slide To Test Function
A fault detector test device includes a test switch including a pivotable lever arm having a first end pivotably connected to rotate about an axis and a second end pivotable in an arc around the axis between an active position and an inactive position. A slide member has a first end accessible by an operator and a second end that cooperates with the second end of the lever arm, the slide member being slideable with respect to the axis of the lever arm such that the second end of the slide member slides in a plane that is substantially tangential to the arc in which the second end of the lever arm pivots. The second end of the slide member and the second end of the lever arm cooperate such that generally planar sliding motion of the slide member is translated into pivoting motion of the lever arm.
VOLTAGE LIMITING DEVICE
The invention relates to a voltage limiting device which has an electromagnetically operable switching device for producing an electrical connection between a first cable terminal and a second cable terminal wherein a first electrical conductor connects the first cable terminal to the one terminal of the switching device and a second electrical conductor electrically connects the second cable terminal to the other terminal of the switching device. The voltage limiting device is characterized in that one of the two electrical conductors comprises an electrically conductive support plate. The expansion of the support plate in the width direction allows, in contrast to an electrical conductor which is characterized by a small width in relation to the length, a current displacement in the width direction. As a result, the forces acting on the conductive parts of the switching device are reduced and the switching contacts are relieved, as a result of which the electrical properties of the voltage limiting device are improved. As an electrical conductor, the support plate improves not only the electrical properties of the voltage limiting device, but as a mounting plate also simplifies the assembly and mounting of the individual components of the voltage limiting device.
External rotary operating mechanism for a circuit breaker
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.
MECHANISM FOR INDIRECT ACCESS TO AN ACTUATOR ON AN APPARATUS DISPOSED WITHIN A HOUSING
The present disclosure envisages a mechanism (100) for indirect access to an actuator (210) on an apparatus (200) disposed within a housing (300). The mechanism (100) comprises a bushing (10), a spring-loaded shaft (20), an arm (30), a first stopper (40) and a pedestal (50). The spring-loaded shaft (20) passes through the bushing (10) and is configured to reciprocate through the annular passage (12). An arm (30) is disposed within the housing (300), and is coupled to the shaft (20). The first stopper (40) is received on the shaft (20) operatively below the arm (30). The pedestal (50) is disposed between the arm (30) and the first stopper (40). The pedestal (50) is configured to facilitate abutment of the arm (30) with the actuator (210). The arm (30) is configured to press the actuator (210) when the shaft (20) is linearly displaced.
Narrow profile circuit breaker with arc interruption
A circuit breaker design allows for the circuit breaker to have an overall width (i.e., measured along the circuit breaker's exposed outwardly-facing surface of its housing) that is narrower than achievable with known typical configurations, while at the same time still providing robust arc interruption capabilities. This is achieved in large part by providing a specific orientation of a moveable contact arm assembly and/or by providing a specific configuration of a current path within the housing.
