Abstract:
A terminal block mounts a plurality of insulation displacement connector type terminal clips formed of an electrically conductive material, each terminal clip having a base portion, an insulation displacing wire-engaging portions projecting outwardly from the base portion and a wire wrap post projecting outwardly from the base portion in a direction opposite to the wire-engaging portion. A block body formed of an electrical insulator material has an upper block section and a lower block section configured for releasably lockingly interengaging the upper block section. The upper block section and the lower block section each have a plurality of generally parallel spaced apart walls defining therebetween a plurality of open-ended cavities. Alignment structures are formed respectively on the upper and lower block sections for aligning respective ones of the cavities, such that one of the open ends of each cavity aligns with an open end of a corresponding cavity in the other of the upper and lower block sections, and such that opposite open ends of each cavity face outwardly when the upper and lower block sections are interengaged. Each cavity of the upper block section is configured for surroundingly receiving one of the terminal clips with the wire wrap post thereof extending toward the lower block section; and each cavity of the lower block section is configured for receiving a protector element therein. A plurality of connectors are provided, each operatively coupled with one of the wire wrap posts and configured for electrical engagement with a protector element.
Abstract:
An insulated terminal block body having a pair of electrical terminals (12, 12') connected by a conductive terminal bus bar (4) is provided with a removably connected overvoltage component (2) having a pair of parallel spaced conductive leads (8, 8') maintained by a pair of resilient members (6, 6') in frictional electrical contact with a portion of the bus bar and with a ground conductor, respectively. In a first embodiment, the ground conductor is a ground bar (5), and in second and third embodiments, the ground conduction comprises the support rail (3) upon which the terminal block body is mounted.
Abstract:
A terminal strip comprising an insulating housing and three busbar sections and comprising a disconnecting blade opening and a plug-type receptacle for a component plug connector is described.The insulating housing has a channel, which leads from the first busbar section to the second busbar section, for receiving an electrically conductive bridging element. The bridging element is electrically conductively connectable or connected to the first and second busbar sections.
Abstract:
An electrical coupling device, such as a surge protector for a rail or other conductive structure, includes a pair of terminals, and a jumper for selectively electrically coupling and decoupling the terminals. Movement of the jumper may expose part of the jumper or one or both of the terminals, such as for use as a test point. A surge module with one or more surge protection features may fit into a base that includes the terminal and the jumper. The module may have an interface feature, such as a protruding post, that prevents engagement with the base if the base is not properly engaged with the rail or other structure.
Abstract:
A terminal block is disclosed that includes a terminal body housing, a plurality of conductive elements arranged within the terminal body to create a continuous electrical path therethrough, and a disconnect switch integral the terminal body, the switch arranged to open the continuous electrical path and expose a terminal.
Abstract:
A Digital Programmable Motor Overload Protector includes a base module and a detachable, removable user interface module interfaced through a serial communications link. The base module provides motor overload analysis through a programmable Digital Signal Processor (DSP) which digitizes real time motor operating conditions, comparing stored user trip and alarm levels against these conditions, communicating the results to the detachable user interface and a multi-drop communications link using the industry standard MODBUS RTU protocol to a facility's automation system. Motor operating conditions, user settings, override conditions, pass events, and resettable parameters are available through the password protected removable user interface module or the multi-drop communications interface.
Abstract:
Apparatus for reducing surge voltages comprising at least one voltage surge suppressor arranged in a holder which has an insulating housing and connecting terminals for connection of external electrical conductors to the apparatus. A metallic foot is so formed on the insulating housing that it, together with an associated pressure member, enables the apparatus to be mounted and rigidly clamped by way of a screw bolt in the manner of a terminal block or the like on a protective earth collector rail. The foot is electrically connected with one terminal of the surge suppressor. The other terminal of the surge suppressor is connected with at least one connecting terminal. On rigidly clamping the apparatus to the collector rail, which at the same time serves as a carrier rail, the required connection between the surge suppressor and the protective ground is automatically produced. In addition to the surge suppressor, the insulating housing may also include at least one electric filter which is also connected with the metallic foot.

Movement of the jumper may expose part of the jumper or one or both of the terminals, such as for use as a test point. A surge module with one or more surge protection features may fit into a base that includes the terminal and the jumper. The module may have an interface feature, such as a protruding post, that prevents engagement with the base if the base is not properly engaged with the rail or other structure. In one embodiment, a threaded rod may serve as the jumper and in one position electrically couples the terminals and in another position electrically decouples the terminals and one end of the threaded rod becomes exposed for use as a test point.
