A method is disclosed. The method includes attaching a light beam emitter to an electrical control assembly having at least one control member that is electrically connected to an electrical component, emitting a light beam from the light beam emitter across the at least one control member, moving the at least one control member between a first position in which the light beam is unblocked by the at least one control member and a second position in which the light beam is blocked by the at least one control member, and connecting the light beam emitter to a notification device via an electrical circuit. The method also includes preventing electrical current flow to the notification device when the at least one control member is in the first position.

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.

The invention relates to a surge protection device with connection elements, an overvoltage protection device (SE1), two contact elements (K1, K2), a slide (AS), a connection plate (B) and a force accumulator (F). The two contact elements (K1, K2) and the overvoltage protection device (SE1) are encased with an electrically nonconducting material on the surface. The electrically nonconducting material leaves open a connection area (A) formed on the second contact element (K2). In a first state, the connection plate (B) is connected to the connection area (A). The slide (AS) is arranged such that it can slide on a surface of the electrically nonconducting material under the action of the force when the thermally softenable contact means softens in a second state, wherein the slide (AS) is displaced between the connection plate (B) and the connection area (A). The electrically nonconducting material is assigned a further function.

The application relates to a charging system, including a number of m chargers each adapted for providing electrical energy to charge an electrical vehicle, whereby m is an integer and m1, a number of n outlet ports each adapted for electrically connecting the electrical vehicle, whereby n is an integer and n2, and a switchable connection matrix device including a number of n outlet port switches each adapted for electrically connecting at least one of the m chargers to one of the n outlet ports and, if m>1, a number of m-1 charger switches each adapted for electrically connecting two of the m chargers, whereby the switchable connection matrix device is adapted for detecting a short-circuit between at least two outlet ports and/or for generating a fault signal if the short-circuit between at least two outlet ports is detected.

A switchgear assembly includes an indicator assembly to indicate whether a movable contact is in an open or a closed position. The indicator assembly includes an indicator body having first and second sections. The indicator body is rotatable to display the first section in the open position and the second section in the closed position. The indicator assembly also includes a drive gear having a first helical spline and coupled to an actuator of the switchgear assembly such that operation of the actuator moves the drive gear, and an elongated driven gear having a second helical spline extending along a length of the driven gear and engaged with the first helical spline of the drive gear such that movement of the drive gear rotates the driven gear. The driven gear is coupled to the indicator body such that rotation of the driven gear causes rotation of the indicator body.

A system includes any number of solid-state circuit breakers that couple between a power supply and an electrical load. The system also includes a housing and the solid-state circuit breakers are disposed within the housing. The housing includes a door sensor that generates a first signal indicative of a position of a door of the housing. The housing also includes an indicator that generates a second signal indicative of a position of a handle of the housing. The system also includes a secondary device communicatively coupled to the solid-state circuit breakers, the door sensor, and the indicator. The secondary device receives the first signal and the second signal and generates an instruction to adjust an operating state of the solid-state circuit breakers based on the first signal and the second signal.

A circuit interrupter having a status indicator providing a current status of the circuit interrupter, the status indicator presenting one of: an On state, an Off state or a Fault state.
