<p>In the world of electrical engineering, ensuring the safety and longevity of your equipment is paramount. The Surge Protection Device (SPD) outlined here is a robust solution designed to protect against voltage spikes in industrial and commercial settings.</p><p>This SPD operates at a rated voltage of 230 V, making it suitable for various applications within that range. It can handle a significant surge current with a rating of 20 kA, providing peace of mind during unexpected electrical surges. The device&#39;s interrupt rating stands at 125 A, ensuring it can effectively break circuits when necessary.</p><p>Built with practicality in mind, this SPD has been crafted from durable thermoplastic material. Its compact dimensions—18 mm wide, 90 mm high, and 66 mm deep—allow for easy integration into existing systems without occupying excessive space. With an IP20 degree of protection, it is safeguarded against solid objects larger than 12.5 mm but should be installed in environments where exposure to dust or moisture is minimal.</p><p>The SPD mounts conveniently on a standard 35 mm DIN rail, simplifying installation processes across diverse setups. Its operational temperature range from -40 to 80 degrees Celsius ensures reliable performance even under extreme conditions.</p><p>Compliance with rigorous standards such as KEMA, VDE, UL, and CSA certifies its quality and reliability in safeguarding your electrical infrastructure. The quick response time of less than or equal to 25 nanoseconds means that the device reacts almost instantaneously to surges.</p><p>For wiring flexibility, the cross-section accommodates different conductor types: up to 1.5 sq-mm for solid/flexible wires and up to 35 sq-mm for stranded wires; flexible connections are supported up to 25 sq-mm.</p><p>Designed as a Type 2 SPD class device according to international classifications, it offers intermediate protection levels suitable for downstream equipment after primary surge arresters have mitigated large surges closer to service entrances or main distribution panels.</p><p>Weighing just 123 grams allows this SPD not only ease of handling during installation but also ensures minimal load on support structures where weight considerations are crucial.</p><p>Finally yet importantly is its ability under duress; having been tested successfully against short circuit currents rated at an impressive figure like our subject’s own threshold – namely clocking-in around twenty-five kiloamperes!</p><p>This comprehensive suite makes it an indispensable component within any sophisticated power management system aiming towards enhanced resilience &amp; extended lifespan alike!</p>
