40 A
A nominal current of 40 amperes (A) is used in photovoltaic, charging and control systems that demand stable and safe power transmission for medium to high loads. This current rating is ideal for DC distributions, inverter connections, wallboxes and power control units.
40 A-rated components ensure reliable conductivity, low power loss and strong circuit protection. They are typically used with 6–10 mm² cables and protected by B40 or C40 circuit breakers. Perfect for charging stations, hybrid PV systems and industrial power setups.
