A lever assembly is for an operating mechanism of an electrical switching apparatus. The electrical switching apparatus includes a number of pairs of separable contacts structured to move from a CLOSED position to a TRIPPED OPEN position in response to a trip condition. The operating mechanism has an enclosure member and a number of biasing elements coupled to the enclosure member. The biasing elements are structured to move the separable contacts from the CLOSED position to the TRIPPED OPEN position. The lever assembly includes a lever member structured to engage the enclosure member, and a component located on the lever member. The component is structured to extend through each of the biasing elements in order to lengthen each of the biasing elements when the separable contacts are in the CLOSED position.

An electrical switching device, including a socket, a holder and electrical contacts housed in the holder. The holder includes a first end and a second end. The device includes a guidance device for guiding the first end of the holder relative to the socket. The device includes a fastener including a head, a tail, a first stem extending from the head to the tail, and a second stem extending from the head. The first stem is configured for passing through the holder and for being inserted at the tail into a first orifice of the socket, in order to retain the first end of the holder relative to the socket. A retaining member is configured for retaining the fastener, in order to rigidly connect the second end of the holder to the socket.

In this method, the voltage outage load-side is an opening of the circuit breaker, and the circuit breaker is able to interrupt the flow of electric current in an electric connection including an electric conductor. The auxiliary unit comprises a current sensor for measuring the intensity of the current flowing in the electric conductor and a first detection means for detecting the voltage outage load-side from the circuit breaker. The method comprises the following steps: measuring the intensity of the current flowing in the electric conductor, detecting the voltage outage load-side from the electric circuit breaker, determining a cause of the detected voltage outage load-side from the circuit breaker, said cause being selected from the group consisting in: an electric overload, a short-circuit and a voltage drop.

Methods, systems, and devices are disclosed for implementing a fiber-waveguide evanescent coupling. In one aspect, a device having integrated photonic components includes a substrate, a waveguide formed on the substrate to include a terminal waveguide portion that terminates at one side of the substrate, and a fiber including a fiber core and fiber cladding surrounding the fiber core, in which at least a portion of the fiber cladding is removed at or near a fiber terminal end to enable optical evanescent coupling via a side surface of the fiber core at the or near the fiber terminal end, the fiber core at the or near the fiber terminal end is placed over the one side of the substrate to be above and to overlap with the terminal waveguide portion of the waveguide to enable optical evanescent coupling via side surfaces of the fiber core and the waveguide.

A circuit breaker having a first micro switch, a second micro switch and a transmission mechanism. The transmission mechanism drives the first micro switch and the second micro switch, which are arranged in a circuit breaker shell. The first micro switch and the second micro switch are arranged on one side of the shell side by side, and a corresponding first transmission rod and a corresponding second transmission rod in the transmission mechanism respectively drive the first micro switch and the second micro switch. Since the circuit breaker is provided with no external device, the space occupied by the circuit breaker is reduced, thereby facilitating construction and installation. Since the two micro switches are built-in side by side, different signals can be simultaneously output.

A multi-purpose mounting assembly is provided. The multi-purpose mounting assembly is structured to be disposed in an electrical switching apparatus housing assembly. The multi-purpose mounting assembly includes a body defining a first mounting assembly and a second mounting assembly. The first mounting assembly includes a first mounting construct. The second mounting assembly includes a second mounting construct. The first mounting construct is structured to support a first electrical component. The second mounting construct is structured to support a second electrical component.

A secondary disconnect assembly is for electrically connecting and disconnecting accessories to an electrical switching apparatus, such as a power circuit breaker. The secondary disconnect assembly includes a terminal block assembly comprising a mounting member, at least one terminal block removably mounted on the mounting member, and at least one accessory plug structured to be removably inserted into the terminal block to be electrically connected to the terminal block. The terminal block and the accessory plug each include a plurality of error-proofing features. The error-proofing features prohibit insertion of the accessory plug into the terminal block unless the accessory plug is correctly disposed in a predetermined orientation.
