Stops and Spacers for DIN Rails
Position terminal blocks, relays, and other components mounted to DIN rails with these stops and spacers. They are often used to create space between components for cooling, make wiring easier, and organize electrical panels and cabinets.
Stops stay fixed in place when you attach them to a DIN rail, keeping your components from sliding along the rail. For the most secure hold, use screw-on stops. As you tighten the screw, it wedges into place against the DIN rail. Snap-on stops are quick to install or remove—just snap them onto the DIN rail.
Group markers mount onto stops—label them for easy identification.
Spacers separate and organize components into groups. They slide along DIN rails, so you can shift components without having to remove the spacers.

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 and DIN 1 rail and can be removed without disrupting adjacent blocks. All have screw-clamp terminals for a secure connection, reducing the chance of wire disconnecting due to vibrations, pulls, or snags. Blocks that meet IP10 shield connections from objects larger than your hand; those that meet IP20 protect against objects larger than your fingers.
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.
Blocks with a fuse holder allow inline fuse wiring to protect components and wires from short-circuit damage.
Blocks with a disconnect tab or knob easily disconnect a circuit without needing to remove installed wire. Use them for testing. Disconnect knobs have a push-button with a through hole, so they can be sealed with wire when they’re disconnected, similar to a lockout tag. This reduces the risk of accidentally connecting the circuit. A test socket lets you try out your circuit. Insert a test plug (sold separately) into the socket, then use a voltage meter to check.
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 prevent movement. Those rated IP20 provide additional protection from objects larger than your fingers.
Jumpers connect terminals on adjacent blocks of 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.

Quick and Secure Modular DIN-Rail Mount Terminal Blocks

The spring-clamp terminals on these blocks make wire installation faster than other types of terminals. Push wire into the spring clamp for a secure connection that withstands vibration and temperature changes. Add as many circuits as you need with these terminal blocks and accessories; blocks mount side-by-side on DIN 3 rail.
Blocks with fuse holder allow inline fuse wiring to protect components and wires from short-circuit damage.
Use blocks with disconnect tab for testing.
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 prevent movement.
Adjacent jumpers connect terminals on adjacent blocks of the same width. Alternate jumpers connect terminals on two blocks of the same width, skipping a block in between.
Numbered marker cards include two of each number (1-50).
Note: Prices are 15% lower when you buy 25 or more of the same size.

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.
