<p>When it comes to safeguarding your electrical systems, selecting the right surge protection device (SPD) is crucial. The NSP Series Surge Protection Device offers a robust solution designed for industrial and commercial applications, ensuring reliability and safety in diverse environments.</p><p>This SPD is crafted to handle a rated voltage of 320 VAC between line and neutral (L-N), and 255 VAC between neutral and protective earth (N-PE). With a rated current capacity of 40 kA for both L-N and N-PE configurations, it provides substantial protection against transient overvoltages that can damage sensitive equipment.</p><p>The NSP Series operates efficiently across three phases, making it suitable for low-voltage power systems. Its DIN Rail mounting type ensures easy installation within standard electrical enclosures, optimizing space with dimensions of 98 mm in length, 72 mm in width, and 65 mm in height. Weighing just 0.2 kg, it&#39;s lightweight yet sturdy enough for demanding applications.</p><p>Engineered to endure harsh conditions, this SPD functions reliably within an operational temperature range from -40&#176;C to 80&#176;C. It also performs well under varying humidity levels from 5% to 95%, catering to diverse environmental needs.</p><p>Compliance with international standards such as IEC 61643-11:2011, UL 1449 Third Edition, and IEEE C62.41.2:2002 underscores its quality assurance credentials. These certifications affirm its capability to meet rigorous safety requirements while delivering optimal performance.</p><p>The voltage protection level stands at less than 1.5 kV (L-N), offering significant reduction in residual voltage during surge events. Additionally, the device can handle lightning impulse currents up to 4 kA (L-N), providing further resilience against extreme electrical disturbances.</p><p>In summary, the NSP Series Surge Protection Device delivers comprehensive surge protection tailored for LV power systems across industrial settings. Its adherence to stringent standards combined with practical design features makes it an ideal choice for professionals seeking reliable protection solutions without compromise on performance or safety compliance.</p>
