When safety, visibility and serviceability matter on the pad or in the field, this 350A Energy Storage Connector shines - literally. The bright orange housing signals high-voltage circuits at a glance while delivering dependable 350A performance through a massive 12.0 mm Radsok contact. Built for large-scale solar farms, wind-turbine battery zones and containerized megawatt storage, this connector simplifies operations and reduces human error during installation and maintenance.
benefits
- Safety first: High-visibility orange housing for fast HV identification during commissioning and service.
- Field-ready: IP67 sealing and UV-resistant nylon ensure years of outdoor exposure with minimal upkeep.
- Fast maintenance: Drawer-style or slide-in deployment enables quick swaps of battery modules without rewiring.
- Energy efficiency: Low contact resistance (0.2 mΩ) and 12.0 mm Radsok contact minimize thermal losses - better round-trip efficiency for your BESS.
