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.
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.

Short-Resistant Terminal Blocks
Recessed screw terminals prevent you from accidentally connecting two circuits with a screwdriver or other tool, causing a short. Blocks can be cut into smaller sections. All meet UL 94 flammability standards.

Enclosure-Mounted Terminal Blocks
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.
Spring-clamp terminals make wire installation faster than screw terminals. Push the wire into the spring clamp for a secure connection that withstands vibration.
ABS plastic and polycarbonate enclosures are lightweight and resist denting, chipping, and cracking. The polycarbonate enclosures also come with cord grips that are watertight. IP65 rated enclosures can be rinsed off. NEMA 4X and NEMA 6 rated enclosures protect against washdowns and weather conditions such as rain, snow and sleet. NEMA 4X enclosures also have increased protection against corrosion, similar to stainless steel.

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.
