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

Quick and Secure Modular DIN-Rail Mount Terminal 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.
Rated UL 94 V-0, all meet flammability standards.
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.
Jumpers connect circuits between blocks to simplify wiring and leave terminals available to connect equipment. Adjacent jumpers connect terminals on adjacent blocks of the same width. Alternate jumpers connect terminals on two blocks of the same width, skipping a block in between.
Marker cards fit into built-in label holders on the blocks. Numbered marker cards include two of each number (1-50).

Terminal Blocks
Mount blocks to a panel or the surface of a machine. Also known as barrier terminal strips. All are rated UL 94 V-0, so they meet flammability standards.
DIN-rail mount blocks also attach to DIN 3 rail.
Covers protect the top of the block and prevent accidental contact with a live circuit. They include mounting clips to place between the block and its mounting screws.
Marker strips extend from underneath the blocks to provide a blank space for labeling.
Jumpers connect side-by-side terminals.
Quick-disconnect adapters convert screw terminal connections into quick-disconnect connections.

Quick and Secure Connect Terminal Blocks
The spring-clamp terminals on these blocks make wire installation faster than other types of terminals. These wire connections also stand up to vibration and temperature changes. Use your finger to release the spring clamp and then push your wire into place. All blocks are rated UL 94 V-0, so they meet flammability standards.
Use DIN rail adapters to mount blocks to DIN 3 rail. Two adapters per block are required, except the two-circuit blocks need only one adapter.

Secure-Connect Circuit Board Terminal Blocks
Secure wires to your circuit board without worrying about them vibrating loose or getting pulled out. Also known as Eurostyle terminal blocks, these blocks use screw-clamp terminals to clamp your wire in place. Insert your stripped wire into a port, then tighten the screw to secure it with the internal clamp. To connect these blocks to your circuit board, directly solder the pins to it. They meet UL 94 V-0 for flame retardance.

With the help of distribution blocks, you can take a high-current wire from your power source and connect it to one or more electrical devices.
Blocks with a screw-clamp terminal input wire connection have a current rating based on NEC table 310-16 using 75° C copper wire.
Blocks with a quick-disconnect load connection let you attach an auxiliary device, such as a horn or light.
Blocks with a detachable cover prevent accidental contact with live circuits.
End stops (sold separately) mount at the end of a group of blocks to prevent movement.
