1500V DC 350A High Voltage Interlock Terminal Connector For Energy Storage Systems
1500V DC 350A High Voltage Interlock Terminal Connector For Energy Storage Systems
The 350A HVIL terminal connector descriptions
Which is a robust, color-coded (black/orange) DC power connector engineered for safe, high-current, high-voltage connections in energy storage and new energy systems. It features copper contacts for superior conductivity, flame-retardant V0 plastic insulation, and an IP54-rated housing. Rated for 1500V DC and 350A maximum current, it delivers reliable performance in harsh environments (-40°C to 125°C) with built-in keying to prevent mis-mating, making it ideal for battery packs, inverters, and power distribution units.

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)
