No need to tighten or loosen any screws—these terminals lock your wiring in place with spring clamps. Insert a slotted screwdriver to release the spring clamp and then push your wire into place. Spring-clamp wire connections withstand vibration and temperature changes. You can add as many circuits as needed with these terminal blocks and accessories; blocks mount side-by-side on DIN 3 rail.

Rated UL 94 V-0, all meet flammability standards.

Grounding terminal blocks facilitate grounding circuits by electrically connecting wires to DIN rail. They shouldn’t be used for applications other than grounding.

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. Adjacent jumpers connect terminals on adjacent blocks of the same width. Marker cards fit into built-in label holders on the blocks. Numbered marker cards include two of each number (1-50).

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 (sold separately) wherever it’s easiest and then plug it into the socket. For more permanent connections, these blocks also have spring-clamp terminals. You’ll need a slotted screwdriver to release the spring clamp that holds the wire in place. Add as many circuits as you need with these blocks and accessories. They mount side-by-side on DIN 3 rail.

All blocks are rated UL 94 V-0, so they meet flammability standards.

Jumpers connect circuits between blocks to simplify wiring and leave terminals available to connect equipment. These jumpers are lateral jumpers, so they connect to blocks in place of wire or in addition to a wire at the terminal connection points.
