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.

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. 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 Distribution Bars

Build your own distribution system for neutral and grounding applications by adding terminal blocks to these bars. Slide blocks onto the bar, also known as a bus bar, and then attach mounting brackets to the bar. All wires make contact with the bar, distributing the current among the terminal blocks.

Terminal blocks have screw-clamp terminals that secure the wire as well as the block to the bar. Blocks are UL recognized for grounding applications.

Distribution Blocks

With the help of distribution blocks, you can take a high-current wire from your power source and connect it to one or more electrical devices.

Blocks with a screw-clamp terminal input wire connection have a current rating based on NEC table 310-16 using 75° C copper wire.

Choose blocks with a bus-bar input wire connection to distribute power from flat conductors without the need for an adapter.

Blocks with a jumper cable terminal connect to other blocks to increase the number of outputs.

Blocks with a quick-disconnect load connection let you attach an auxiliary device, such as a horn or light.

Blocks with a detachable cover prevent accidental contact with live circuits.

End stops (sold separately) mount at the end of a group of blocks to prevent movement.
