Edge plates

End plates are accessories for mounting terminal blocks. Next to baffles, keepers and clips, they are the most commonly used accessories, whose most important function is to prevent accidental access to the conductive parts of the terminal block.

End plates - a special type of baffle

When used to terminate connector assemblies, outrigger plates are manufactured to be installed specifically on the outermost connector and are visually distinct from baffles. Since their purpose is to prevent accidental contact with conductive parts, due to the importance of the function, every connector and accessory manufacturer offers them in their product range.

End plates as a means of protection against direct contact

The primary role of terminal blocks is to prevent access to live parts by people through accidental contact as well as to devices and other conductive parts (e.g. loose wires or accidentally removed screws). In switching technology it is realized by means of basic and additional protection. The former include

  • insulation of active parts, e.g. insulation of conductors and cables,

  • enclosures, fences and barriers,

  • placing live parts out of reach,

  • use of residual current devices (RCD) as a supplementary measure.

The terminal block is an example of a barrier belonging to the basic means of protection against direct contact, and its task is the insulation of the terminal block.

Like other barriers and enclosures used in electrical switchgear, the terminal block must be permanently mounted in such a way that inadvertent access to live parts is prevented. They can be dismantled only by means of tools or hands, however always in an intentional, not random way. It is worth stressing that the task of barriers against accidental access is not to prevent intentional and deliberate access to active parts. Barriers and enclosures prevent loss of life and health due to accidental touching of conductive parts, as well as failures and material losses caused by resulting short circuits.

Partition and end plates - short-circuit protection

In addition to protection against direct contact, the end plates also prevent short circuits of the terminal block installed in the assembly. Although not all terminal blocks are designed to allow access to metal parts that are conductive or may periodically be live, most do not protect against accidental short circuits. In such connectors, the use of an end plate is a safety necessity.

Short-circuit protection is also provided by spacer plates, which form a physical barrier between separate connector sections. They are often constructed in such a way that, when installed between adjacent connectors, they prevent a splicing between two separate sections. At the same time, many of them also allow for electrical connection through elements that can be broken off. The provision of these possibilities makes baffles a useful and at the same time universal accessory in connection technology.

To meet customer needs, many manufacturers provide connectors in different colours. Green and yellow are usually reserved for protective connectors, but the other colours make it possible to visually distinguish the individual sections, which facilitates both the assembly of the electrical switchgear and its subsequent modernisation.

How are the edge plates used?

Extension panels available on the market, just like partitions, are always compatible with connectors of a given manufacturer, both technically (matching fastenings, shape, colours) and in terms of material (the same strength parameters, fire resistance, resistance to chemicals). Most often their manufacturing technology ensures the possibility of assembly in all batches of the product, or at least in a few selected ones - for example PSU or PSD partitions from ERGOM.
