<p>When considering robust protection for your electrical systems, understanding the specifications of a Surge Protection Device (SPD) is crucial. This SPD is designed with precision to safeguard single-phase TT-A systems against voltage spikes and surges, ensuring operational continuity and safety.</p><p>Operating at a rated voltage of 255 VAC, this device efficiently handles current surges with its impressive rated current capacity of 12.5 kA between Line-Neutral (L-N) and 25 kA between Neutral-Protective Earth (N-PE). The SPD&#39;s lightning current carrying capability stands out with an ability to manage up to 25 kArms for L-N connections and a substantial 100 kArms for N-PE connections. This makes it particularly effective in environments prone to frequent or severe electrical disturbances.</p><p>The response time is remarkably swift at less than or equal to 100 nanoseconds, offering near-instantaneous protection against transient overvoltages. Its maximum voltage protection level caps at &lt;=1.5 kV, further enhancing its protective capabilities by limiting the surge voltages that can pass through.</p><p>Designed for easy installation on DIN rails, this SPD ensures convenience without compromising on performance. With dimensions measuring just 0.1 mm in length, 0.07 mm in width, and 0.04 mm in depth, it offers a compact footprint ideal for space-constrained setups while maintaining a solid build with a weight of 0.3 kg.</p><p>The device boasts an IP20 degree of protection rating which indicates that it provides basic protection against solid objects larger than 12mm but should be installed where exposure to moisture or dust ingress is not prevalent as it&#39;s suited more towards indoor installations within controlled environments.</p><p>In summary, this Surge Protection Device combines efficiency with reliability—making it an excellent choice for those seeking dependable defense against electrical surges in industrial or commercial settings requiring single-phase TT-A system compatibility.</p>
