A fusible switch disconnect device includes a housing adapted to receive at least one fuse therein, and a switchable contact for connecting the fuse to circuitry. A tripping mechanism and control circuitry are provided to move the switchable contact to an open position in response to a predetermined electrical condition.

A remote control device may be mounted to a structure. The remote control device may include a control unit, a base, a faceplate, an adapter, and a mounting plate. The adapter may be configured to be attached to the faceplate. The adapter may be configured to be secured to the structure. The mounting plate may float between the adapter and the structure when the adapter is secured to the structure. The mounting plate may include a frame, a mounting tab, and a plurality of spring arms. The mounting tab may extend from the frame, for example, a platform on the frame. The mounting tab may be configured to prevent rotation of the base of the remote control device when the base is attached to the mounting plate. The plurality of spring arms may be configured to bias the mounting tab away from the structure.

An adapter for installing at least one accessory part into an electrical switch. The accessory part has at least one interface and the electrical switch has a housing and at least one actuation element. The adapter has at least one deflection gear mechanism, which, when the adapter is installed in the housing of the electrical switch, is arranged in an operatively connecting manner between the at least one interface of the accessory part and the at least one actuation element of the electrical switch.

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” Lock-Off feature. It is integrated to one or more housing components of the circuit breaker not as a separate component to achieve most simplicity and least space used as compared to an “add-on” accessory based Lock-Off feature. The “integrated” Lock-Off feature has a feature 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 that is configured to move relative to the feature. The built-in Lock-Off mechanism in combination with the Lock-Off feature is configured to prevent handle from being turned ON with the use of padlock. The padlock prevents circuit breaker from turning ON by impeding the handle from moving to an ON-position.

A disconnecting switchgear has three mutually exclusive positions II-0-I, with position II energizing the load circuit, position 0 de-energizing the load circuit and position I grounding the circuit, which reduces the electrical risk when interacting with an electrical panel. The switchgear includes a control interconnected with a body, where the control includes a gripping mechanism with an electrical labelling element, an extension mechanism, a locking mechanism and indicator labels; the body includes a group of external electrical conductors or connection terminals, a group of internal electrical conductors or poles, an earth short-circuit electrical conductor, displays of electrical quantities, luminous indicators, and sight glasses for viewing moving poles; electrical conductors and electrical contacts interconnected with a drive shaft and the latter to a power-transmission mechanism.

A maintenance bypass (MBP) system for an uninterruptible power supply (UPS) includes a first switch having at least three positions that provide different couplings of a power source, a load, a power input of a UPS and a power output of a UPS and including a first contact set configured to indicate at least one transition between positions of the at least three positions. The system further includes a second switch configured to enable transition of the first switch between at least two of the positions and including a second contact set configured to indicate actuation of the second switch. The first switch may include a rotary switch and the second switch may include a pushbutton switch.

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.
