An electrical device includes a case defining an interior space. The case includes a sidewall and a cover. The sidewall defines an opening therethrough to provide access to the interior space. The electrical device also includes a power connector coupled to the case and disposed at least partially within the interior space. The power connector is coupleable to a cable extending through the opening into the interior space of the case. The electrical device further includes a shield removably coupleable to the case. The shield includes an engagement feature and a wall. The engagement feature is arranged to engage the case. The wall is arranged to at least partially cover the opening when the shield is coupled to the case such that the wall and the cable are spaced apart a distance that is less than a width of the opening when the cable is coupled to the power connector.

A solenoid actuator is provided which has a lower housing having a generally axially extending portion joined to an end cap with a central opening. An upper housing of the solenoid actuator is formed from a flat stock with a main body with radially extending slot separated legs which are plastically deformed into a cylindrical portion for press fit acceptance with an outer diameter of lower housing axially extending portion.

A switch with an integrated overcurrent protection element can include multiple arc gap between the contacts when opening the circuit during overload protection and switching operations. The switch can include an overcurrent protection element which can make contact with two contact terminals, and which can change to a different shape upon exposure to an overcurrent condition. The overcurrent protection element can also be moved in a direction normal to the two contact terminals between a first position and a second position through the use of a rotary switch to selectively place the overcurrent protection element in contact with the two contact terminals.

An electrical protection device, including a movable contact, connected to an electrical circuit, a switching handle, and an electronic control unit. The device further includes an electrical link element, connecting the movable contact and the electronic control unit, a switch, a mechanical link element, connected to the switching handle. The electronic control unit is configured to measure the first voltage and the second voltage, compare the first voltage and the second voltage to determine the cause of opening of the electrical circuit among manual opening and fault opening, send a first signal if the cause of opening is manual opening and send a second and/or third signal if the cause of opening is fault opening.

A guard assembly is for an electrical switching apparatus of an electrical system. The electrical system includes a number of conductors each having an insulated portion and an exposed portion that meet at a junction. The electrical switching apparatus includes a housing and a number of terminals connected to the exposed portion of a conductor. The guard assembly comprises: an interconnect member coupled to the housing; and a number of guard members each comprising: a first portion coupled to the interconnect member, and a second portion extending from the first portion away from the housing, the second portion comprising: a first distal end located at the first portion, and a second distal end opposite and distal from the first distal end. Each of the guard members has an opening. The opening receives a conductor. Each junction is located between a second distal end and a terminal.
