Phoenix Contact UK 5 Feed-Through Terminal Block, Screw Connection, 4 mm², 800 V, 32 A, Grey, DIN Rail Mount, 2 Connections, 1 Potential, PA Insulation, UL 94 V0

In control cabinets and distribution boxes, reliable wire termination is non-negotiable. The Phoenix Contact UK 5 feed-through terminal block solves the challenge of creating secure, vibration-resistant screw connections for conductors up to 4 mm². Its compact design and DIN rail mounting make it a staple in industrial wiring, building automation, and panel building.

Who is it for

This terminal block is built for electrical engineers, panel builders, and maintenance technicians who need a dependable, space-saving solution for power distribution and signal wiring. It suits applications in machine building, process control, and energy management where IEC-rated components are required.

Tips

Use a torque screwdriver set to 0.6–0.8 Nm to ensure a secure connection without damaging the conductor. For stranded wires, ferrules are recommended to prevent splaying. The terminal block can be grouped with other UK 5 blocks using standard end covers and partition plates for a neat, organized assembly.
