400 A

A nominal current of 400 amperes (A) is used in high-current photovoltaic, battery and industrial power systems that require safe and efficient handling of extreme continuous loads. It is ideal for main DC distributions, NH3/MEGA fuses, copper busbars and heavy-duty switches.

400 A-rated components provide exceptional conductivity, thermal stability and minimal resistance. Recommended conductor cross-sections of 300–400 mm² with terminal sizes up to M16 ensure reliable operation up to 1000 V DC. Perfect for industrial energy hubs, battery storage systems and high-power charging infrastructure.
