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.

Terminal blocks meet IP20 to protect connections from objects larger than 12.5 mm, such as fingers.

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. End stops rated IP20 provide additional protection from objects larger than 12.5 mm, such as fingers.

Jumpers connect terminals on adjacent blocks of the same width. Noninsulated jumpers can be cut to size.

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.

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. Terminal blocks meet IP20 to protect connections from objects larger than 12.5 mm, such as fingers.

Spring-clamp terminals make wire installation faster than screw-clamp terminals. Push the wire into the spring clamp for a secure connection that withstands vibration.

Blocks with fuse holder allow inline fuse wiring to protect components and wires from short-circuit damage.

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.

Jumpers connect terminals on adjacent blocks of the same width. Noninsulated jumpers can be cut to size.

Modular Channel-Mount Terminal Blocks

Mount these NEMA-style blocks to a channel and add as many circuits as you need.

End covers fit on the open side of a block to prevent accidental contact with a live circuit. One end cover is required per group of terminal blocks.

Channels accommodate up to 48 terminals per foot.

Channel clamps secure a group of terminal blocks to a channel. A clamp is required on each end of a group of blocks.

Jumpers connect side-by-side terminals.

Terminal Blocks

Mount blocks to a panel or the surface of a machine. Also known as barrier terminal strips.

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.
