Short-Resistant Easy-Disconnect Terminal Blocks
Plug
Socket
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.

Touch-Safe Terminal Blocks
Terminal Block
Marker Card
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.

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.
