DIN Rail Terminal Blocks
Versatile, reliable connections for control and power distribution
Altech offers a complete range of DIN-rail terminal blocks designed for control panels, automation, and machinery wiring. Available in screw-clamp, spring-clamp, and push-in technologies, they provide secure, vibration-resistant connections that save time and space. Options include feed-through, ground, fuse, disconnect, and component carrier blocks, plus stud/ring styles for heavy-duty, high-current applications.
Slim, modular designs maximize panel density—handling up to 600 V while keeping footprints as narrow as 3.5 mm. Accessories like jumpers, separators, test plugs, and labeling systems make installation and maintenance faster, safer, and more organized.
