This feed-through terminal block (item number 281-654) focuses on 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. A stripping length of 9 to 10 mm is required for this feed-through terminal block. This product uses CAGE CLAMP® technology. The CAGE CLAMP® universal connection delivers reliable, maintenance-free connection technology to connect all types of conductors using a cage tension spring. No pre-treatment of the conductors is necessary, for example by crimping on bootlace ferrules. Depending on the type of conductor, this feed-through terminal block is suitable for conductor cross-sections of 0.08 mm² to 4 mm². This feed-through terminal block is actuated using an operating tool. https://elecena.pl/product/29654452/281-654-4-conductor-feed-through-terminal-block-4-mm-blue 2025-12-29 https://elecena.pl/product/29654452/281-654-4-conductor-feed-through-terminal-block-4-mm-blue 2026-01-10
