<p>This Surge Protection Device (SPD) is engineered to safeguard your electrical systems from power surges, ensuring reliability and efficiency in both industrial and commercial settings. With a rated voltage of 230 VAC, it is designed for three-phase systems, providing robust protection with a rated current capacity of up to 150 kA between line and neutral (L-N), as well as neutral to protective earth (N-PE).</p><p>The SPD features a digital display that offers clear visibility of operational parameters, making monitoring straightforward for technical personnel. Its shunt connection type facilitates easy integration into existing setups. Built to withstand demanding environments, this device boasts an IP20 degree of protection, indicating its suitability for indoor panel mounting applications.</p><p>Measuring 200 mm in width and depth with a height of 80 mm, the compact design allows for efficient use of space within panels while maintaining accessibility. The unit operates effectively across a wide temperature range from -40&#176;C to 70&#176;C and can handle humidity levels between 5% and 95%, ensuring reliable performance in diverse conditions.</p><p>Compliance with international standards such as IEC 61643-11:2011, AS/NZS 1768:2007, UL 1449 3rd Edition, and IEEE 62.41.2:2002 underscores the device’s quality and safety credentials. Constructed from durable aluminium material weighing just 2.7 kg, it combines lightweight properties with the strength necessary for long-term use.</p><p>The SPD&#39;s rapid response time—less than 25 nanoseconds between L-N connections and under 100 nanoseconds between N-PE—ensures quick action against transient overvoltages. It also features modes of protection including L-L (line-to-line), L-N (line-to-neutral), and N-PE (neutral-to-protective earth), providing comprehensive coverage against various surge scenarios.</p><p>For installation integrity, tightening torques are specified at two levels: one at 0.5 N-m for lighter applications and another at a more robust setting of 2 N-m when required by system demands. The interrupt rating is set at an impressive 100 A while the fuse rating stands at a solidly safe level of 80 A.</p><p>Additional technical specifications include a contact configuration featuring Single-Pole Double Throw (SPDT) capabilities which enhance versatility in application scenarios requiring specific switching actions or redundancy measures. Furthermore, the voltage protection level remains below &lt;750V on L-N paths offering peace of mind during high-stress events such as lightning strikes where impulse currents may reach up to19 kA on L-N lines or peak at30 kA through N-PE pathways.</p><p>Overall this SPD represents an ideal choice for those seeking dependable surge suppression solutions backed by rigorous testing protocols aligned with global benchmarks—a testament not only towards engineering excellence but also practical usability tailored specifically around real-world needs without compromise on safety nor functionality fronts alike!</p>
