Designed for installation at the main distribution board, it safely dissipates high-energy lightning impulse currents (Iimp) while effectively limiting transient overvoltages, ensuring seamless protection across multiple threat levels. This model is specifically configured for DC power systems, with a rated voltage of 1000V\/1200V DC and a 3-pole design, making it ideal for photovoltaic (PV) systems, energy storage installations, and other DC applications. Compliant with IEC\/EN 61643-11 standards, the TZG40-T1T2 offers reliable, space-saving protection for residential, commercial, and industrial DC power distribution. Customization options, including alternative voltage or current ratings and RS485 communication functionality, are available upon request.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cspan
