<p>When it comes to safeguarding your electrical systems, the SDN Series Surge Protection Device (SPD) offers a robust solution designed for industrial and commercial applications. This SPD is engineered to protect sensitive equipment from voltage spikes, ensuring reliability in environments where operational continuity is critical.</p><p>The SDN Series SPD operates efficiently across a three-phase system with a rated voltage of 275 VAC between line and neutral (L-N) and 255 VAC between neutral and protective earth (N-PE). It&#39;s capable of handling a substantial rated current of 200 kA for L-N connections and 150 kA for N-PE, making it suitable for demanding installations that require high surge protection capabilities.</p><p>Designed with shunt connection type, this device effectively diverts excess voltage away from your equipment. Its IP20 degree of protection ensures safety against solid objects over 12 mm while facilitating easy maintenance. The unit&#39;s compact dimensions—80 mm in width, 141 mm in height, and 69 mm in depth—allow it to fit neatly on DIN rails without occupying excessive space within control panels.</p><p>The SDN Series is built to withstand harsh conditions with an operational temperature range stretching from -40 to 70 degrees Celsius. This makes it adaptable to diverse environments—from freezing cold warehouses to hot manufacturing floors—without compromising performance.</p><p>Compliance with international standards such as IEC 61643-11, AS/NZS 1768, UL 1449, and IEEE 62.41.2 underscores its quality and reliability. These certifications assure users that the SPD meets rigorous safety requirements essential for protecting valuable electrical infrastructure.</p><p>For those concerned about voltage protection levels, the SDN Series provides peace of mind with a level less than &lt;1.5 kV (L-N), minimizing potential damage during transient events. Additionally, it can handle lightning impulse currents up to 25 kA (L-N) and up to 30 kA (N-PE), further enhancing its protective capabilities against extreme surges often encountered during thunderstorms or power anomalies.</p><p>In summary, the SDN Series Surge Protection Device stands as an effective shield against electrical surges. With its impressive specifications tailored for high-demand scenarios and compliance with key industry standards, it&#39;s an excellent choice for professionals seeking reliable surge protection solutions that ensure longevity and stability of their electrical systems without unnecessary frills or complexities inherent in other devices on the market today.</p>
