Rated IP20, these blocks have recessed terminals to prevent accidental contact with live circuits. These recessed terminals also reduce the chance you’ll cause a short by accidentally connecting two circuits with a screwdriver or other tool. Use these blocks with ring terminals, spade terminals, or stripped wire; you can attach them without removing the screw.

All blocks fit onto DIN 3 rail.

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.

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.

A single row of terminals fits in narrow spaces. Also known as barrier terminal strips. All blocks are rated UL 94 V-0, so they meet flammability standards.

Note: Voltages listed apply only when the included insulation strip is attached to the bottom of the block.

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.

Best for equipment requiring regular servicing, these blocks disconnect without having to remove any wiring thanks to their plug-and-socket design. Their recessed terminals prevent shorts by reducing the risk you’ll connect two circuits with a screwdriver or other tool. All blocks can be cut into smaller sections. They’re rated UL 94 V-0, so they meet flammability standards.

For a complete terminal block, you’ll need a plug and socket.

Save time when wiring connections in a junction box. These blocks come already installed in an enclosure. All enclosures are IP and NEMA rated to seal out dust and protect against corrosion. They meet UL 94 flammability standards.

ABS plastic and polycarbonate enclosures are lightweight and resist denting, chipping, and cracking. The polycarbonate enclosures also come with cord grips that are watertight. Aluminum enclosures are more durable than plastic ones, so they’re good for harsh environments where debris would damage plastic enclosures.

IP65 rated enclosures can be rinsed off. IP67 rated enclosures withstand temporary submersion. NEMA 4X and NEMA 6 rated enclosures protect against washdowns and weather conditions such as rain, snow and sleet. NEMA 12 rated enclosures withstand lightly splashing water, oil, and coolant.

Inspect the terminal block and wiring without opening the cover. Because the terminal block is already installed in the enclosure, you save time when wiring connections in a junction box. The enclosure meets NEMA 6 and IP65 for protection from dirt, washdowns, temporary submersion, and weather conditions such as rain, snow, and sleet. Rated UL 94 V-0, all meet flammability standards.

Solder the pins on these blocks directly to your circuit board and connect the screw terminals to stripped wires, ring terminals, or spade terminals. They’re also known as barrier terminal strips. These blocks meet UL 94 V-0 for flame retardance.

Jumpers connect side-by-side terminals.

Quick-disconnect adapters convert screw terminal connections into quick-disconnect connections.

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.

Quickly disconnect these terminal blocks without having to remove any wires. Their plug and socket connections work best for equipment that you service frequently. Screw-clamp terminals keep your wire in place even when pulled, snagged, and exposed to vibration. Solder the pins on the socket directly to your circuit board. Blocks are designated UL 94 V-0 for flame retardance.

For a complete terminal block, you’ll need a plug and socket.

Make electrical connections through a panel—blocks mount in a cutout and have terminals on both sides. Rated UL 94 V-0, they meet flammability standards.

Lever-clamp terminals make installation and maintenance quick and convenient. Lower the lever to secure a wire; lift the lever to disconnect it.

Connect thermocouple wires without soldering or splicing. The terminals on these terminal blocks are made from same materials as thermocouples to ensure no signal is lost. Also known as barrier strips, they shield connections from each other to keep them neat and minimize the chance of short circuits. Choose a terminal block that matches your thermocouple type. You should also make sure the equipment you’re connecting it to is also compatible with the same thermocouple type.

For easy wiring, each end is labeled positive or negative. Mount these terminal blocks to a panel or machine using the mounting holes.
