ATC-UKK-160
- Category: DISTRIBUTION TERMINAL BLOCKS
- Brand: ATC INDIA
- Minimum quantity: 1
- Price: ₹ 480
The ATC-UKK-160 is a compact, industrial-grade unipolar distribution block rated at 160A and 690V. Featuring a robust, flame-retardant PA66 housing and a solid tinned brass conductor, it splits a single heavy incoming power line into six or more distinct output connections. Equipped with an IP20 finger-safe transparent cover, it optimizes rail space while ensuring high electrical safety in heavy-load control cabinets.
Product Details
- Model Designation: ATC-UKK-160 (Alternative: UKK-160A)
- Maximum Current Rating: 160 Amperes continuous load
- Rated Insulation Voltage: 690V AC / DC (IEC compliant)
- Terminal Wiring Configuration (Typical 1-In / 6-Out Layout):
- Input Port (x1): Accepts heavy cables from 10mm² to 50mm² (approx. 8 AWG to 1/0 AWG)
- High-Output Ports (x2): Accepts cables from 2.5mm² to 16mm²
- Standard-Output Ports (x4): Accepts cables from 2.5mm² to 16mm² (or 10mm² depending on specific terminal layout)
- Housing Material: Premium polyamide Nylon 66 (PA66), UL94V-0 self-extinguishing flame-retardant rating
- Internal Block Material: High-conductivity tinned brass block with high-tensile hex/slotted steel tightening screws
- Protection Class: IP20 (Finger-safe protection when properly latched)
Key Features
- High Power-to-Size Ratio: Handles up to 160A of current while maintaining a very slim physical footprint on the rail, eliminating the need for traditional, bulky open busbars.
- Tinned Brass Core Protection: The specialized tin-plating over a solid brass core prevents surface oxidation, allowing it to be safely paired with both copper and aluminum heavy-gauge wires.
- Visual Safety Shroud: The clear, hinged flip-cover protects personnel from accidental contact while enabling rapid visual inspection of the wire entry points and screw terminations.
- Flexible Dual Mounting: Snaps instantly onto standard 35mm DIN-rails or can be screwed flat onto a backplate panel via the integrated base mounting holes.
- Interlocking Modular Design: Features side grooves that allow multiple UKK-160 modules to lock together seamlessly, letting you construct 3-Phase (L1/L2/L3) or 4-Pole (L1/L2/L3+N) distribution sets.
Applications
- Industrial Automation & MCC Panels: Centralizing and splitting heavy main feeds down to independent motor drives (VFDs), contactors, and soft starters.
- Commercial Main Breaker Panels: Acting as a bridge to feed rows of smaller sub-breakers from a high-amp incoming line.
- Solar and Energy Storage Systems: Used inside large DC/AC combiner boxes, battery storage racks, and commercial inverter cabinets to aggregate high currents.
- Heavy HVAC Controls: Safely distributing power out to multiple commercial chillers, industrial compressors, and high-kilowatt heating arrays.
