Modular DIN-Rail Mount Terminal Blocks

Mix and match these terminal blocks to get the exact number of circuits you need in a single setup. Add blocks for thermocouples, fuses, and grounding wire as needed. The blocks clip side by side onto DIN rail in control panels, creating tidy rows of circuits that you can identify and access on the spot.

The screw-clamp terminals flatten your wire so it stays put when vibrated or pulled. If you need to change wiring frequently without adjusting a screw, consider a quick-connect terminal block with spring-clamp or lever-clamp terminals.

Fuse Terminal Blocks with Screw-Clamp Terminals

Install a fuse in the built-in fuse holder so excess current doesn't damage your equipment. If the current exceeds the limit, the fuse will blow and cut power to connected components.

Blown Fuse Indicator—A light goes on when the fuse blows, so you can spot an overloaded circuit without cutting power or touching equipment.

Covers—Snap onto the exposed side of a terminal block to prevent accidental contact with a live wire.

End Stops—Mount at the end of a group of terminal blocks so they don't slide when vibrated or bumped.

Bar Jumpers—Metal poles create an electrical connection between blocks, so you can connect multiple components with a single wire. Blocks must be the same width for the jumpers to fit. Cut jumpers to size with a hacksaw or high-force wire cutter. Add covers so jumpers don't touch the screws on the outermost blocks.

Insulation—Terminal blocks with insulated jumpers maintain their IP20 rating to prevent shocks and short circuits. Blocks with noninsulated jumpers lose their IP20 rating for touch protection because the jumpers introduce exposed metal to the circuit.

Quick-Connect Modular DIN-Rail Mount Terminal Blocks

Pop wire in and out of these terminal blocks without adjusting a screw. Lift the clamp with a screwdriver or built-in lever, then release the clamp down onto the wire. Once clamped in place, the wire will stay put when vibrated, bent, or pulled.

Space-Saving Modular DIN-Rail Mount Terminal Blocks

These handle the same voltage and power as our other modular blocks while taking up about half the vertical space. Snap them onto DIN 2 rail (also known as mini rail), which is lower in height than DIN 3 rail.

The screw-clamp or spring-clamp terminals flatten your wire so it stays put when vibrated or pulled. For an even stronger and more conductive connection, crimp a terminal or wire ferrule onto the end of the wire.

Mix and match blocks to get the exact number of circuits you need in a single setup. Add terminal blocks for fuses and grounding wire as needed. The blocks clip side by side onto DIN rail in control panels, creating tidy rows of circuits that you can identify and access on the spot.

A screw presses the clamp onto the wire for a secure hold.
