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.

Terminal Blocks with Screw-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.

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.

Terminal Blocks

Also known as barrier terminal strips, these blocks have dividers to separate live wires and keep your setup tidy. Mount them directly onto control panels, enclosures, and equipment.

A screw or stud connection creates a tight hold on the wire. You can insert stripped wire directly or attach a terminal to prevent damage from the fastener. Ring, spade, and hook terminals fit around the shank and hang on tightly, even in high-vibration setups. Pin terminals, blade terminals, and wire ferrules are easier to secure with the screw or stud. However, they don't stay put as well as other terminals when vibrated or pulled.

For DIN 3 Rails—Unlike other surface-mount terminal blocks, these have a notch that snaps onto DIN 3 rail. You can also screw them directly onto your control panel or other surface.

Covers—Snap onto the top of a terminal block to prevent accidental contact with a live wire. These covers include mounting clips that fit between the block and mounting screws.

Markers—Label your terminal block connections so you can identify them at a glance. These markers extend from underneath the terminal block.

High-Temperature Terminal Blocks

These ceramic terminal blocks keep their shape and strength at temperatures up to 1,200° F—over four times higher than standard blocks. Mount them to surfaces in ovens, kilns, and other heat-generating equipment.

Screw-Clamp-Terminal Wire Connection—The clamp flattens the wire to resist pullout and vibration better than screw terminals. For an even stronger and more conductive connection, crimp a terminal or wire ferrule onto the end of the wire.

Quick-Connect Terminal Blocks

Snap wire into place with a clamp instead of fussing with a screw. Release the spring clamp with a screwdriver, insert the wire, and push the clamp back down for a secure hold. For an easier fit in the small gaps in the block, attach a ferrule, pin terminal, or blade terminal before installing.

DIN Rail Mounting Adapters—Install terminal blocks on DIN 3 rail with these mounting brackets. You can mount two-circuit terminal blocks with one adapter. For all other blocks, you'll need two.

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.

Terminal Blocks with Spring-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.

Adjacent Jumpers—Metal poles create an electrical connection between adjacent terminal blocks, so you can connect multiple components with a single wire. Blocks must be the same width for the jumpers to fit.

Alternate Jumpers—Connect terminals on two blocks of the same width, skipping a block in between. This reduces wire clutter and gives you flexibility to adjust your set-up in the future.

Space-Saving Terminal Blocks

These single-row terminal blocks connect the same number of circuits as double-row blocks, but in a narrower footprint. Also known as barrier terminal strips, they have dividers to separate live wires and keep your setup tidy. Mount them directly onto control panels, enclosures, and equipment.

You can screw down your stripped wire directly or attach a terminal to prevent damage from the screw. Ring, spade, and hook terminals fit around the screw and hang on tightly, even in high-vibration setups. Pin terminals, blade terminals, and wire ferrules are easier to slip under the screw head, but they don't stay put as well as other terminals when vibrated or pulled.

Note: Stick the included insulation strip to the bottom of the block before installing. The voltage listed applies only when the strip is attached.

Terminal Blocks for Thermocouples

Unlike other terminal blocks, these blocks connect to thermocouple wire without distorting or destroying the signal. The metal in each terminal matches the metal of a specific thermocouple wire type. The ends of the blocks are labeled positive or negative so you know which end of the wire to attach.

Also known as a barrier strip, this type of terminal block has dividers to separate live wires and keep your setup tidy. Mount the blocks directly onto control panels, enclosures, and equipment. The screw-clamp terminals flatten your wire so it stays put when vibrated or pulled.

Plug-and-Socket Circuit Board Terminal Blocks


Plug	Socket

Cut power with the pull of a plug when you need to swap out equipment or adjust your circuit. You can wire the plug away from the terminal block, then pop it into the socket you've already installed. Pins on the bottom of these blocks are spaced to match the layout of circuit boards. Solder them onto your board for a secure hold. You'll need one plug and one socket for a complete terminal block.

The screw-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.

Touch-Safe Plug-and-Socket Terminal Blocks


Plug	Socket

These terminal blocks cut power when you pull the plug while protecting you from shocks. The terminals are recessed, so you can't accidentally touch them when installing or adjusting wire. You can wire the plug away from the block, then attach it to the socket you've already installed. Blocks can be cut into smaller sections. You'll need one plug and one socket for a complete terminal block.

You can screw down your stripped wire directly or attach a terminal to prevent damage from the screw. Ring, spade, and hook terminals fit around the screw and hang on tightly, even in high-vibration setups.

Quick-Connect Plug-and-Socket Modular DIN-Rail Mount Terminal Blocks

Cut power with the pull of a plug when you need to swap out equipment or adjust your circuit. One of the openings on these blocks is a socket, so you can wire a plug outside the enclosure and then attach it to the socket that’s already in place.

The other connections are spring clamps, so you can pop wire in and out of these terminal blocks without adjusting a screw. Lift the clamp with a screwdriver, then release the clamp down onto the wire. Once clamped in place, the wire will stay put when vibrated, bent, or pulled.

Mix and match these terminal blocks to get the exact number of circuits you need in a single setup. Add blocks for 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.
