This feed-through terminal block (item number 281-904) enables a fast, reliable connection. In industrial or building applications, the feed-through terminal blocks enable electrical conductors to be connected quickly and safely. Depending on the version, they are suitable for classic through-wiring or potential distributors. Only conductors with a stripping length of 9 and 10 mm can be connected to this feed-through terminal block. This product uses CAGE CLAMP® technology. The reliable, maintenance-free CAGE CLAMP® universal connection makes it possible to connect all types of conductors with a cage tension spring without the need for pre-treating the conductors. Crimping of bootlace ferrules is therefore not required. Depending on the type of conductor, this feed-through terminal block is suitable for conductor cross-sections of 0.25 to 4 mm². This feed-through terminal block is actuated using an operating tool. https://elecena.pl/product/29654450/281-904-2-conductor-feed-through-terminal-block-4-mm-blue 2025-12-29 https://elecena.pl/product/29654450/281-904-2-conductor-feed-through-terminal-block-4-mm-blue 2026-01-10
