The assembly device includes a screw head holding device for holding a screw head of the fixation screw, the assembly device being configured to be arranged inside a cavity of the housing of the molded case circuit breaker in such a way that a screw head of a fixation screw arranged at the screw hole for mounting the molded case circuit breaker to the bus bar is engageable with the screw head holding device in an engagement direction. Furthermore, a circuit breaker system is disclosed including a molded case circuit breaker and an assembly device. Moreover, a method is disclosed for mounting a molded case circuit breaker to a bus bar.

An electrical switching apparatus includes a body and a display apparatus. The body has a housing, a handle partially extending through the housing, separable contacts located within the housing, an operating mechanism structured to open and close the separable contacts, a main printed circuit board located within the housing, and a number of electrical rating settings associated with the main printed circuit board. Each of the number of electrical rating settings has a magnitude. The display apparatus is electrically connected to the main printed circuit board and is structured to display the magnitude of at least one of the number of electrical rating settings.

A circuit breaker includes an electrically insulative case including a first end and a second end opposite the first end. The circuit breaker further includes an end cover selectively installable on both the first and second ends of the electrically insulative case. The end cover includes a wall defining at least one opening for receiving a removable shield, a first end connectable to the electrically insulative case first end, and a second end connectable to the electrically insulative case second end.

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 switch seat body structure and a manufacturing method thereof. The switch seat body structure is simplified and can be easily manufactured to enhance the resistance of the switch seat body against the external damaging force. The switch seat body structure includes a main body for assembling with an internal component of the switch. The main body is an assembly of a metal head section and a nonmetal belly section. The metal head section has a shoulder section, a skirt section connected with the shoulder section and a subsidiary shoulder section formed on the skirt section. The nonmetal belly section is overlaid and connected on at least a part of the skirt section or the entire skirt section, whereby the nonmetal belly section is connected with subsidiary shoulder section to form an integrated structure.

An information display system for a switching device having a handle includes a cover for the switching device and a faceplate. The cover includes an opening sized to allow passage of the handle. The faceplate is configured to carry information about the switching device. The faceplate is rotatable with respect to the cover to change an orientation of the information.

An airtight switch adapted for an airtight device comprises an enclosure and a lid structure which are adapted to be joined with each other at a junction plane. The airtight switch includes a slider disposed at one of the enclosure or the lid structure. The airtight switch includes a contact element disposed at the other of the enclosure or the lid structure. The contact element has a sloped surface, and the slider selectively abuts against the sloped surface. The airtight switch includes a linear drive device adapted to drive the slider to move linearly in a sliding direction. The sliding direction is parallel to the junction plane and non-perpendicular to a normal vector of the sloped surface. The airtight switch is adapted to be applied in an airtight device needing a switch with good sealing and airtightness.
