Product Introduction

The TZG40-T1T2 is a high-performance surge protective device that integrates both Type 1 (T1) and Type 2 (T2) protection into a single compact unit, delivering comprehensive defense against direct lightning strikes and induced surge voltages. 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. With a robust surge handling capacity of up to 50kA (Imax) and flexible pole configurations (1P to 4P), this device is suitable for a wide range of power distribution systems. Compliant with IEC/EN 61643-11 standards, the TZG40-T1T2 offers reliable and space-saving protection for residential, commercial, and industrial applications. Customization options, including alternative voltage or current ratings and RS485 communication functionality, are available upon request.
