Use with DIN 2 rail. Add as many circuits as you need with these terminal blocks and accessories.

Touch-Safe Terminal Blocks

Rated IP20, these blocks have recessed terminals to prevent accidental contact with live circuits.

Terminal Blocks

Mount blocks to a panel or the surface of a machine. Also known as barrier terminal strips.

Space-Saver Terminal Blocks

A single row of terminals fits in narrow spaces.

Short-Resistant Terminal Blocks

Recessed screw terminals prevent you from accidentally connecting two circuits with a screwdriver or other tool, causing a short.

High-Temperature Short-Resistant Terminal Blocks

Made of ceramic, these blocks withstand high-temperature applications that reach up to 1110° F such as ovens and furnaces. They have recessed screws to reduce the chance you’ll cause a short by accidentally connecting two circuits with a screwdriver or other tool.

Short-Resistant Easy-Disconnect Terminal Blocks

Best for equipment requiring regular servicing, these blocks disconnect without having to remove any wiring thanks to their plug-and-socket design. Their recessed screws prevent shorts by reducing the risk you’ll connect two circuits with a screwdriver or other tool.

Enclosure-Mounted Terminal Blocks

Save time when wiring connections in a junction box; these blocks come already installed in an enclosure.

Enclosure-Mounted Terminal
Blocks with See-Through Cover

Inspect the terminal block and wiring without opening the cover.

Through-Panel Terminal Blocks

Blocks mount in a cutout and have terminals on both sides.

Circuit Board Terminal Blocks

Solder the pins on these blocks directly to your circuit board and connect the screw terminals to stripped wires, ring terminals, or spade terminals.

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.

Harsh Environment High-Current Distribution Bars

Protect connections against corrosion.These bars are tin-plated copper and have stainless steel terminals.

High-Current Distribution Posts

Distribute up to 150 amps from the center stud terminal to the eight screw terminals around it.

Set Screw Lugs

Tighten the set screw for a secure connection without crimping. Mount lugs to a screw.

Stacked Set Screw Lugs

Save space on your mounting surface by installing wire vertically.

Lay-In Set Screw Lugs

Mount these lugs to a surface to create electrical connections without needing to cut or splice the conductor wire. For a secure connection without crimping, tighten the set screw onto the wire.

Insulated Set Screw Lugs

To prevent short-circuiting with nearby wire, a plastic cover insulates the barrel on these lugs. Tighten the set screw for a secure connection without crimping.
