What are terminal blocks used for?

They provide fixed, insulated connection points where conductors terminate and interconnect inside a panel or enclosure.

How are they mounted?

DIN rail blocks clip onto a standard rail, while barrier blocks are fastened to the mounting plate or chassis.

Which connection types are available?

Screw clamp, spring clamp, and push-in types cover different conductor sizes and assembly speeds.

What variants exist?

Feed-through, protective earth, and disconnect variants serve through circuits, earth paths, and isolatable connections.

Why is marking important?

Labeling each terminal with the circuit reference supports wiring, testing, and maintenance in the panel.
