The Siemens 5SD7412-2 is a high-performance lightning arrester designed to provide robust protection for electrical systems against overvoltages caused by lightning strikes and switching operations. This Type 1 lightning arrester is suitable for use in 3-conductor networks (L, N, PE) and is engineered to safeguard installations and equipment in both residential and industrial environments.

With a nominal discharge current of 12.5 kA and a maximum discharge current of 50 kA, the 5SD7412-2 ensures reliable performance under extreme conditions. It operates at a nominal voltage of 240 V AC and can handle continuous operating voltages up to 335 V AC (L-N) and 264 V AC (N-PE). The device features a protection level of 1.2 kV between N and L, providing effective suppression of transient overvoltages.

The 5SD7412-2 is designed for easy installation on a standard 35 mm DIN rail, making it a versatile addition to any electrical distribution system. Its compact dimensions (35.6 mm width, 89.8 mm height, and 77.5 mm depth) and lightweight construction (328 g net weight) allow for seamless integration into existing setups.

Constructed from durable PA 6.6 and PBT materials, the 5SD7412-2 boasts a high degree of protection (IP20) and is rated for operation in a wide temperature range from -40 °C to 80 °C. It is compliant with IEC 61643-11 and EN 61643-11 standards, ensuring adherence to international safety and performance requirements.

Ideal for use in TT and TN-S distribution systems, the Siemens 5SD7412-2 lightning arrester is an essential component for protecting electrical infrastructure from the damaging effects of overvoltage events.
