Brass terminal blocks

Terminal blocks are typically used inside switchboards or electrical cabinets for earthing, where small cable cross-sections are required; terminal blocks are a compact and economical solution compared to, for example, copper bars.

Due to their construction, they allow a very high density of cable connections, which is especially useful when there are many terminals to be connected, or in the case of cables coming from two different sides. Some models are provided with connections for cable lugs up to 95 mm².

They can be installed either vertically or horizontally, and are easy to shorten according to the space available inside the electrical equipment. Some products, e.g. MRS5000, are already designed with dimensions suitable for installation in the control cabinets of the major manufacturers on the market.

It is also possible to fix the terminal blocks directly onto a copper bar at a terminal, allowing the rest of the copper bar to be used for larger cable cross-sections.

Generally, the terminal blocks are fixed to the enclosure structure by means of the DZM metal spacers, but if there is a need to isolate them from the enclosure wall, the MRS 7000 series supports, or the CPH series or ISO series insulators can be used.
