400A Copper Busbar 30mm x 4mm x 300mm
400A Copper Busbar 30mm x 4mm x 300mm
Premium Grade Copper Busbar
Dimensions: 30mm (Width) × 4mm (Thickness) × 300mm (Length)
High-Performance Power Distribution for Switchboards, Industrial Panels & Renewable Energy
Engineered for Maximum Conductivity & Reliability
When high currents demand zero compromises, precision engineering matters. Our 30 x 4mm x 300mm Copper Busbar is manufactured from top-tier, high-conductivity electrolytic copper (ETP Grade / Cu-ETP), designed to deliver superior thermal and electrical performance in demanding power distribution applications.
Whether you're building custom electrical switchboards, upgrading industrial control panels, or wiring high-power solar and EV inverter systems, this busbar provides a robust, low-resistance backbone for your circuit.
