<p>When considering surge protection for your industrial or commercial setup, this Surge Protection Device (SPD) offers a reliable solution. Designed to safeguard electrical installations from transient overvoltages, it operates efficiently within a rated voltage of 230/400 V and can handle a rated current of 20 kA. </p><p>The device is built with versatility in mind, featuring a mounting type compatible with the standard 35 mm DIN Rail, making installation straightforward and adaptable to existing systems. With dimensions of 72 mm in width, 90 mm in height, and 66 mm in depth, it fits comfortably into compact spaces without compromising on performance.</p><p>Constructed from robust thermoplastic material, the SPD ensures durability while maintaining safety standards. It boasts an IP20 degree of protection which is adequate for most indoor applications where exposure to dust or water is minimal. The operational temperature range from -40 to 80 degrees Celsius further underscores its capability to perform under varied environmental conditions.</p><p>Safety and compliance are critical aspects of any electrical component. This SPD meets KEMA and UL standards and approvals, providing assurance that it adheres to stringent international safety benchmarks. Its response times are impressively swift at &lt;=25 ns for L-N connections and &lt;=100 ns for N-PE connections, ensuring rapid action against voltage spikes.</p><p>In terms of performance metrics like interrupt rating and short circuit current capacity, this device stands out with ratings of 125 A and 25 kA respectively. These figures reflect its ability to withstand significant electrical disturbances without failure.</p><p>The cross-sectional accommodation caters to various wire types: up to 1.5 sq-mm solid/flexible wires; up to 35 sq-mm stranded wires; and up to 25 sq-mm flexible wires—offering flexibility in wiring configurations during installation.</p><p>Voltage protection levels are crucial when evaluating SPDs; this unit provides a level not exceeding 1.75 kV for L-N lines and not more than 1.5 kV for N-PE lines—effectively reducing the risk of damage from overvoltage events.</p><p>Classified as Type 2/Class II SPD according to industry standards, it&#39;s designed primarily for use downstream of primary lightning arrestors or other upstream devices—ideal for protecting sensitive equipment within secondary distribution panels.</p><p>Weighing just 436 g allows easy handling during installation while ensuring stability once mounted—a practical balance between heftiness required by industrial-grade components yet light enough not hinder manual operations during setup or maintenance tasks.</p>
