Installation Method --- Panel/surface mount installation
The orange housing is fixed to the equipment panel or enclosure using four corner mounting holes with screws. The integrated metal terminal (threaded stud or through-hole on top) is bolted directly to a copper busbar or power cable lug. The black mating connector inserts into the orange base with a secure press-fit/snap-in connection (labeled “PRESS”). Color-coded keying ensures correct polarity and prevents incorrect mating. No special tools required beyond standard fasteners.
Application Scenario
- Battery Energy Storage Systems (BESS)
- Electric Vehicle (EV) battery packs and high-voltage power distribution
- Solar and wind energy storage inverters
- Grid-scale renewable energy integration
- Industrial DC power supplies and converters
- High-power DC charging stations
- Any high-voltage DC connection requiring secure interlocking, high current, and reliable environmental protection
