High Current Handling – 300 Amps
This terminal is optimized to withstand a continuous current of 300A, making it ideal for large-scale battery arrays and power-intensive energy storage applications. Whether you’re running an inverter, a backup power system, or a commercial ESS, this terminal is built for long-lasting performance.
Rugged Black Polycarbonate Shell
Encased in a flame-retardant, industrial-grade polycarbonate shell, the terminal offers superior protection against electrical hazards, physical impacts, and corrosion. The black color designates it for negative polarity, helping to prevent wiring errors and improve visual organization.
Hex Nut Fastening for Secure Connections
Equipped with a heavy-duty hex bolt and washer, the FX-300A ensures strong and stable electrical connections, reducing the risk of power loss due to vibration or loose terminations. Perfect for bus bar, battery lug, or cable-to-terminal mounting.
Compact Mounting Base
With its space-saving design and rear-entry wiring, the FX-300A is suitable for tight battery compartments and can be mounted on panels or racks using standard screws.
