The Citel DLU2-06D3 (Article Number 640402, 74260) is a 4-pole combined surge arrester utilizing diode and gas discharge tube technology. Specifically designed for RS422 applications, this device provides robust circuit protection classified under arresters Type C2 and D1. It features a nominal voltage (Un) of 6 V and a C3 protection level (Up) of 20 V. The DLU2-06D3 delivers a D1 lightning impulse current (Iimp) of 5 kA using a 10/350 µs waveform per data line (DA), a C2 nominal discharge current (In) of 5 kA using an 8/20 µs waveform per DA, and a maximum discharge surge current (Imax) of 20 kA using an 8/20 µs waveform per DA. Engineered for high-speed communication lines, the unit maintains a capacitance (C) of less than 25 pF and a rapid response time of under 1 ns. It is constructed for streamlined integration with installation dimensions of 1 TE.
