Phoenix Contact CLIPLINE UK 35N Heavy Power Terminal Block

The Phoenix Contact CLIPLINE UK 35N is a 35 mm² heavy-power screw-clamp terminal block rated at 125 A / 1000 V AC to IEC 60947-7-1, designed for high-current bus termination, main power feed marshalling, and large motor power interfaces in Saudi industrial LV switchgear assemblies and main distribution boards. The UK 35N accepts conductors from 6 mm² to 50 mm² — covering the full range from 6 mm² motor circuit protector (MCP) feeds to 50 mm² copper busbar-to-cable transition points in Saudi MCC incomers and transformer secondary LV panels. The double-hole landing design clamps the conductor across two screw-and-plate contacts in sequence, distributing the full 125 A current path across a larger contact area and reducing contact resistance to a level that maintains conductor temperature below the maximum 70°C allowed for PVC-insulated cables at the rated 125 A current. This is particularly important in Saudi panel applications where ambient panel temperatures can reach 45–55°C in summer, reducing the thermal headroom available for I²R heating at the terminal connection.

The UK 35N is the upper end of Phoenix Contact's standard CLIPLINE UK-N family (UK 6N, UK 10N, UK 35N, UK 70N), and its 20 mm pitch DIN rail footprint reflects the larger conductor cross-section while remaining compatible with the overall CLIPLINE UK-N accessory system — end plates, phase separators, and marker card holders are shared across the UK-N family, allowing Saudi panel builders to use one unified accessory system from 2.5 mm² instrument terminals through 35 mm² heavy power terminals without stocking multiple accessory families. The UK 35N includes a built-in phase separator groove that accepts standard DIN-rail separator inserts, providing 230 V system-to-system segregation within the same terminal strip section — important in Saudi 3-phase 380 V panel sections where phase-to-phase touch-voltage of 660 V (line-to-line) requires phase-segregation inserts between terminal positions.

The UK 35N is specified for the heavy power termination tier in Saudi MCC, switchroom LV panel, and main distribution board applications — particularly in ARAMCO production facilities where 400 A to 1000 A LV panel main busbars must interface to large-gauge cable via terminal block before entering the cable ladder and running to field-mounted switchgear. ARAMCO's Ras Tanura refinery, Juaymah NGL facility, and Abqaiq processing plant LV main distribution boards use Phoenix Contact UK 35N and UK 70N terminals for their busbar-to-cable interface sections. SABIC's heavy-industrial plants in Jubail — including SIPCHEM, Saudi Kayan, and Petrokemya — use UK 35N in their main LV distribution board heavy-cable termination sections. NEOM OXAGON's port LV power distribution equipment, which must handle the heavy electrical loads of port cranes and industrial HVAC systems, specifies heavy-power DIN-rail terminals capable of 100 A+ for its main distribution termination.

Razz Middle East supplies UK 35N in Riyadh and Jeddah and provides the full CLIPLINE UK-N family from UK 6N through UK 70N for complete Saudi panel power termination requirements. Our team provides terminal sizing to IEC 60947-7-1 and Saudi Electrical Code requirements, torque specification documents for ARAMCO Inspection approval, and phase-separator insert selection guides for 380 V and 690 V Saudi panel applications. All UK 35N supplies carry Phoenix Contact CE declarations, IEC 60947-7-1 test reports, and SASO import conformity documentation for Saudi Customs clearance.
