Modular DIN-Rail Mount Terminal Blocks

Use with DIN 3 rail. Add as many circuits as you need with these terminal blocks and accessories.

Quick and Secure Modular
DIN-Rail Mount Terminal Blocks

No need to tighten or loosen any screws—these terminals lock your wiring in place with spring clamps.

Clamp-On Modular DIN-Rail Mount Terminal Blocks

Quickly troubleshoot or change wiring without any tools. These terminal blocks have a lever clamp that you flip up to insert wiring and flip down to lock it in place.

Modular DIN-Rail Mount Terminal
Blocks with LED Status Indicator

Visually confirm your circuits are working as expected. These terminal blocks have integrated LEDs that indicate if your circuits are powered or not, helping you troubleshoot issues.

Connector-Compatible Modular
DIN-Rail Mount Terminal Blocks

One of the connections on these terminal blocks is a socket instead of a traditional terminal, making it easy to swap out equipment or change your wiring even in small enclosures. Instead of having to attach wire inside the tight space of your enclosure, you can wire a connector wherever it’s easiest and then plug it into the socket.

Touch-Safe Terminal Blocks

Rated IP20, these blocks have recessed terminals to prevent accidental contact with live circuits.

Modular Mini DIN-Rail Mount Terminal Blocks

Use with DIN 2 rail. Add as many circuits as you need with these terminal blocks and accessories.

Terminal Blocks

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

Space-Saver Terminal Blocks

A single row of terminals fits in narrow spaces.

Quick and Secure Connect Terminal Blocks

The spring-clamp terminals on these blocks make wire installation faster than other types of terminals. These wire connections also stand up to vibration and temperature changes.

Short-Resistant Terminal Blocks

Recessed screw terminals prevent you from accidentally connecting two circuits with a screwdriver or other tool, causing a short.

High-Temperature Short-Resistant Terminal Blocks

Made of ceramic, these blocks withstand high-temperature applications that reach up to 1110° F such as ovens and furnaces. They have recessed screws to reduce the chance you’ll cause a short by accidentally connecting two circuits with a screwdriver or other tool.

Short-Resistant Easy-Disconnect Terminal Blocks

Best for equipment requiring regular servicing, these blocks disconnect without having to remove any wiring thanks to their plug-and-socket design. Their recessed screws prevent shorts by reducing the risk you’ll connect two circuits with a screwdriver or other tool.

Terminal Blocks with Built-In Configurable Jumpers

Customize these blocks’ wiring as your application changes. They come with jumpers that connect terminals on the same block, either across or next to one another.

Enclosure-Mounted Terminal Blocks

Save time when wiring connections in a junction box; these blocks come already installed in an enclosure.

Enclosure-Mounted Terminal
Blocks with See-Through Cover

Inspect the terminal block and wiring without opening the cover.

Through-Panel Terminal Blocks

Blocks mount in a cutout and have terminals on both sides.

Circuit-Board-Mount Terminal Blocks

Solder the pins on these blocks directly to your circuit board.

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.

Harsh Environment High-Current Distribution Bars

Protect connections against corrosion.These bars are tin-plated copper and have stainless steel terminals.

Modular Distribution Bars

Build your own distribution system by adding terminal blocks to these bars.

Distribution Posts

Stack multiple ring or spade terminals on the stud terminal; the current flows through the stacked terminals.

High-Current Distribution Posts

Distribute up to 150 amps from the center stud terminal to the eight screw terminals around it.

Wire Splicing Connectors

Clamp-On Wire Splicing Connectors

Press down on the clamp to connect wires and pull it up to disconnect.

Push-On Wire Splicing Connectors

Push stripped wires into connectors for a reliable connection that's faster to install than twisting or crimping.

Multi-Way Taps/Splices

Tap and splice multiple wires together at the same time.

Sealed Multi-Way Taps/Splices

Tap and splice multiple wires in temporarily wet environments and up to six feet underground.

Clamp-On Wire Splicing Connector Assortments

Keep splicing connectors on hand for two, three, or five wires.

Distribution Blocks for Nano M8 and Micro M12 Cords

Distribution Blocks for Nano
M8 and Micro M12 Cords

Connect multiple M8 and M12 cords to create a network between equipment. These blocks are often used to send signal and power to proximity switches and sensors.

Temperature and Humidity Monitoring

Terminal Blocks for Thermocouple Wire

Connect thermocouples to extension wire or instrumentation.

Terminal Blocks for RTD Wire

Connect RTD wire leads to conduit or instrumentation.

Stops and Spacers for DIN Rails

Position terminal blocks, relays, and other components mounted to DIN rails with these stops and spacers.

DIN-Rail Mount Fuse Blocks

DIN-Rail Mount Fuse Blocks
for UL Class CC Midget Fuses

DIN-Rail Mount Fuse Blocks for UL Class J Fuses

DIN-Rail Mount Fuse Blocks for UL Class CF Fuses

DIN-Rail Mount Fuse Blocks for Midget Fuses

Sized to fit non-UL Class Midget Fuses, these fuse blocks are suitable for switchboard panels, small motors, and transformers.

DIN-Rail Mount Fuse Blocks for
1,000V DC Fast-Acting Fuses

Designed for the solar industry, these fuse blocks can handle the requirements of high-voltage DC applications.

Surface-Mount Fuse Blocks

Fuse Blocks for UL Class Fuses

Fuse Blocks for Automotive Fuses

An insulating cover prevents contact with live circuits. Use these fuse blocks with standard and maxi blade-style automotive fuses.

Fuse Blocks for Midget Fuses

Designed for use with non-UL Class midget fuses, these are more compact than fuse blocks for standard sized fuses.

Fuse Blocks for Glass-Tube
and Ceramic-Tube Fuses

These fuse blocks fit ¼" glass- and ceramic-tube fuses.
