Core Innovations
- Ultra-High Current Capacity
- Engineered for 232A continuous load with minimal contact resistance (<0.3 mΩ), reducing thermal stress and energy loss by 15% compared to conventional designs.
- Copper conductors plated with tin-nickel alloy ensure superior conductivity and corrosion resistance in harsh environments (humidity, chemicals, vibration).
- Robust Mechanical Design
- Self-locking hex-screw mechanism: groove to generate reverse torque, preventing wire loosening under extreme vibration.
- Steel pressure frame (hardened quenched) withstands high clamping force, enabling secure connections for rigid/flexible cables without tube terminals.
- Modular Expansion System
- Central bridging slots: Enable horizontal busbar integration for parallel circuits (e.g., solar arrays or MCCs) without external jumpers.
- Tap-off compatibility: Supports UFB1 splitter terminals to connect smaller cables (e.g., 35 mm²) alongside main conductors.
- Safety & Reliability
- 1000V reinforced isolation between poles, with arc-resistant PA66 housing (UL94 V-0).
- Prismatic compensation blocks (UFB1) ensure airtight connections for flat conductors, eliminating oxidation risks.
- Smart Installation Features
- Tool-free snap-fit mounting on TH35/G-type rails, with reinforced brackets for 95 mm²+ cables.
- Laser-engravable markers (ZB series)and color-coded housings for phase identification.
Applications
- Energy Grids: Transformer junctions, busbar extensions, and substation switchgear.
- Renewables: Wind turbine controllers (232A rotor circuits), solar farm combiners.
- Industrial Automation: Motor control centers (MCCs), rolling mill systems, and crane power feeds.
- Transportation: Railway traction units and airport ground power systems469.
