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.

Modular Mini DIN-Rail Mount Terminal Blocks
Add as many circuits as you need with these terminal blocks and accessories. The terminal blocks clip onto DIN 2 rail. All blocks are rated UL 94 V-0, so they meet flammability standards. They’re IP20 rated to protect connections from objects larger than 12.5 mm, such as fingers.
Spring-clamp terminals make wire installation faster than screw-clamp terminals. These wire connections also stand up to vibration and temperature changes. Insert a slotted screwdriver to release the spring clamp and then push your wire into place.
Blocks with a fuse holder protect components and wire from short-circuit damage by enclosing the fuse.
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. They’re adjacent jumpers, so they connect terminals on adjacent blocks of the same width. Noninsulated jumpers can be cut to size.
Marker cards fit into built-in label holders on the blocks.

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.
Grounding terminal blocks facilitate grounding circuits by electrically connecting wires to DIN rail. They shouldn’t be used for applications other than grounding.
Blocks with a fuse holder protect components and wire from short-circuit damage by enclosing the fuse.
Blocks with a blown fuse indicator light up so you’ll know if your fuse is blown without having to touch equipment or disconnect power.
Blocks with a disconnect tab or knob easily disconnect a circuit without needing to remove installed wire. Use them for testing. Blocks that are 51.5 mm or 63.5 mm high have a single circuit with multiple screw-clamp terminals, so they save space on DIN rail.
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. Lateral jumpers are connected to blocks in place of a wire or in addition to a wire at the screw-clamp connection terminal points. Insulated jumpers eliminate the risk of your finger coming into contact with a live circuit, so they’re touch safe.
Marker cards fit into built-in label holders on the blocks.
