The ATC-UKK-400 is a highly compact, industrial-grade unipolar distribution block rated for a substantial 400A continuous load and 690V insulation capacity. Built with a premium, flame-retardant UL94V-0 PA66 nylon housing and a highly conductive solid brass core, this single-pole module effortlessly splits one ultra-heavy gauge supply conductor into 11 distinct localized branch circuits. It features an IP20 finger-safe transparent cover designed to streamline space-constrained control cabinets.
Product Details
- Model Designation: ATC-UKK-400 (Alternative: UKK-400A)
- Maximum Current Rating: 400 Amperes continuous load (IEC standard) / Approx. 335A–355A under UL/CSA testing conditions.
- Rated Insulation Voltage: 690V AC / DC
- Terminal Wiring Matrix (1-In / 11-Out Multi-Wire Layout):
- Input Terminal Feed (x1): Accepts highly robust main cables up to 185mm².

- Medium-Output Branch Nodes (x5): Accepts cables up to 16mm².
- Standard-Output Branch Nodes (x4): Accepts cables up to 10mm².
- Casing Material: Polyamide Nylon 66 (PA66), self-extinguishing flame-retardant bracket housing.
- Internal Block Material: Pure copper/brass alloy, heavily tinned to resist corrosion and oxidation.
- Protection Class: IP20 Touch-Proof / Finger-Safe rating.
Key Features
- Massive Line Splitting Efficiency: Consolidates power by taking one ultra-heavy gauge incoming cable and splitting it smoothly across 11 output channels. This entirely replaces sprawling, unsafe traditional open copper busbars.
- Dual-Metal (Al/Cu) Compatibility: Thanks to the specialized tin-plating over its heavy brass alloy core, the terminal block resists galvanic oxidation, making it perfectly safe for both heavy aluminum or standard copper wiring feeds.
- Transparent Inspection Window: A clear, flip-open polycarbonate top shroud allows maintenance technicians to conduct rapid visual checks for proper wire seating or thermal stress marks without shutting down the panel.
- Universal 35mm Rail Clip: Integrates snap-on mounting feet designed for instant deployment onto standard 35mm top-hat DIN rails. It also includes dual integrated base holes for direct screw-down mounting onto an internal chassis backplate.
- Space-Saving Modular Nesting: The side locking rails enable multiple UKK-400 blocks to slide and click together. This allows technicians to cleanly structure distinct multi-phase configurations side-by-side.
Applications
- Heavy Industrial Distribution Boards (MDB): Serving as the central junction within main switchboards, dividing raw utility or generator feeds to lower-tier branch circuit breakers.
- Large Motor Control Centers (MCC): Splitting high-amperage lines down to feed rows of heavy-duty variable frequency drives (VFDs), industrial pump contactors, and high-horsepower soft starters.
- Commercial HVAC Control Panels: Managing and isolating high-kilowatt electrical heating elements, large chilling towers, and commercial compressors.
- Solar Combiner Arrays & Energy Storage: Utilized in utility-scale solar inverter cabinets and commercial battery storage banks to bridge or step down high DC/AC currents safely.
