Core Features
- High-Capacity Design
- Optimized for 150A continuous load with low contact resistance (<0.5 mΩ), minimizing heat generation and energy loss.
- Electroplated tin-copper alloy clamps resist corrosion and maintain conductivity in humid/vibratory conditions.
- Flexible Bridging Solutions
- Central bridge slots enable horizontal busbar connections for parallel circuits without external jumpers 1.
- Supports tap-off connections for smaller cables (e.g., 16 mm²) alongside main conductors.
- Secure Installation
- Dual-purpose mounting: Snap-fit attachment to TH35 or G-type rails for tool-free assembly.
- Anti-slip cage clamp design prevents wire loosening under shock/vibration.
- Safety & Compliance
- 1000V reinforced isolation between poles reduces arc risk.
- Certified to IEC, and RoHS standards; flame-retardant housing (UL94 V-0).
- Traceability & Customization
- Laser-engravable marking strips (1–600 numbering) for circuit identification.
- Optional color-coded housings (gray/yellow/green) for phase differentiation.
Applications
- Power Distribution: Main switchgear, transformer links, and busbar extensions.
- Renewable Energy: Solar inverters, wind turbine controllers.
- Industrial Systems: Motor control centers (MCCs), heavy machinery, and rail traction systems.
- Infrastructure: Substations, airport/railway power grids, and data centers.
