    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.

    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.
