Quick-Connect Modular DIN-Rail Mount Terminal Blocks

Pop wire in and out of these terminal blocks without adjusting a screw. Lift the clamp with a screwdriver or built-in lever, then release the clamp down onto the wire. Once clamped in place, the wire will stay put when vibrated, bent, or pulled.

Mix and match these terminal blocks to get the exact number of circuits you need in a single setup. Add blocks for thermocouples, fuses, and grounding wire as needed. The blocks clip side by side onto DIN rail in control panels, creating tidy rows of circuits that you can identify and access on the spot.

Fuse Terminal Blocks with Spring-Clamp Terminals

Install a fuse in the built-in fuse holder so excess current doesn't damage your equipment. If the current exceeds the limit, the fuse will blow and cut power to connected components.

Blown Fuse Indicator—A light goes on when the fuse blows, so you can spot an overloaded circuit without cutting power or touching equipment.

Covers—Snap onto the exposed side of a terminal block to prevent accidental contact with a live wire.

End Stops—Mount at the end of a group of terminal blocks so they don't slide when vibrated or bumped.

Adjacent Jumpers—Metal poles create an electrical connection between adjacent terminal blocks, so you can connect multiple components with a single wire. Blocks must be the same width for the jumpers to fit.
