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.
With their flexibility, durability, and broad selection, Altech DIN-rail blocks deliver dependable performance across industries from factory automation to power distribution.
