Modular DIN-Rail Mount Terminal Blocks
Add as many circuits as you need with these terminal blocks and accessories. The terminal blocks clip onto DIN 3 rail and can be removed without disrupting adjacent blocks. Some also clip onto DIN 1 rail. All have screw-clamp terminals for a secure connection, reducing the chance of wire disconnecting due to vibrations, pulls, or snags. Rated UL 94 V-0, all meet flammability standards. Blocks that meet IP10 shield connections from objects larger than your hand; those that meet IP20 protect against objects larger than your fingers.
End covers fit on the open side of a block to prevent accidental contact with a live circuit.
End stops mount at the end of a group of blocks to keep them in place. Those rated IP20 provide additional protection from objects larger than your fingers.
Marker cards fit into built-in label holders on the blocks.
