Disconnect Terminal Blocks

DIN rail multi-level terminal block with push-in spring connections designed for compact wiring and signal distribution in industrial control panels.

Disconnect terminal blocks are available as disconnect and knife-disconnect types from Phoenix Contact in screw, Push-X, spring cage, and push-in connection technologies with integrated test points, disconnect levers, removable links, and fuse holder options for safe circuit isolation, testing, and troubleshooting in DIN rail-mounted industrial control panels and automation systems.

Disconnect terminal blocks are designed to safely interrupt electrical circuits without requiring conductors to be removed. Commonly installed in control cabinets, these terminal blocks provide a practical method for isolating circuits during maintenance, testing, and troubleshooting. By allowing technicians to access circuits directly at the terminal block using standard test equipment, they help reduce risk while improving efficiency during system service and diagnostics.

Phoenix Contact CLIPLINE complete disconnect and knife-disconnect terminal blocks feature integrated test points that eliminate the need to remove conductors or bridges for circuit measurement, providing an additional test option directly at the terminal point. The double-function shaft allows disconnect terminal blocks to be freely combined with feed-through, fuse, high-current, and other CLIPLINE terminal block types within the same terminal strip, supported by uniform bridging, marking, and test accessories that reduce logistics costs and simplify panel organization. Screw connection disconnect terminal blocks provide maximum contact force and maintenance-free performance through the Reakdyn principle, while Push-X versions enable tool-free wiring of rigid and flexible conductors from 0.34mm² to 25mm² without ferrules.

Disconnect terminal blocks are DIN rail-mounted and engineered to fit into compact panel layouts. Many designs incorporate disconnect levers, removable links, or integrated fuse holders to provide flexible circuit separation and added protection in modular wiring systems and multi-circuit control panels where clear isolation and safe operation are essential. All Phoenix Contact disconnect terminal blocks are tested throughout the manufacturing process and approved for a wide range of national and international standards, providing high long-term stability and reliability in demanding industrial applications.
