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.

Blocks with a fuse holder protect components and wire from short-circuit damage by enclosing the fuse.

Blocks with a blown fuse indicator light up so you’ll know if your fuse is blown without having to touch equipment or disconnect power.

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.

Jumpers connect circuits between blocks to simplify wiring and leave terminals available to connect equipment. Blocks must be adjacent to each other and the same width. Bar jumpers screw down into designated sections on terminal blocks. You can cut them to size. Where listed, end covers should be used on the outermost blocks in the connection. Insulated jumpers eliminate the risk of your finger coming into contact with a live circuit, so they’re touch safe.

Marker cards fit into built-in label holders on the blocks.

No need to tighten or loosen any screws—these terminals lock your wiring in place with spring clamps. Insert a slotted screwdriver to release the spring clamp and then push your wire into place. Spring-clamp wire connections withstand vibration and temperature changes. You can add as many circuits as needed with these terminal blocks and accessories; blocks mount side-by-side on DIN 3 rail.
