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.

Parameters chart

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
