<p>When it comes to safeguarding electrical systems, selecting the right surge protection device (SPD) is crucial. This particular SPD is designed for industrial and commercial applications, providing robust protection with its impressive specifications.</p><p>Operating at a rated voltage of 690 V and a rated current of 35 kA, this SPD offers reliable performance in demanding environments. Its IP20 degree of protection ensures that it is shielded against solid objects larger than 12 mm, making it suitable for indoor use where dust isn&#39;t prevalent.</p><p>Measuring 54 mm in width, 183 mm in height, and 101 mm in depth, this compact unit can be easily integrated into existing setups without taking up excessive space. Despite its sturdy build, it weighs only 908 g thanks to its thermoplastic construction which balances durability with lightweight properties.</p><p>One of the standout features is its rapid response time of less than or equal to 100 ns. This allows the device to react swiftly to surges, minimizing potential damage to connected equipment. The fuse rating stands at 35 A which complements its protective capabilities by ensuring additional circuit safety.</p><p>The cross-section compatibility includes options for various wiring needs: accommodating stranded wires up to 50 sq-mm, flexible wires up to 35 sq-mm, and both solid and flexible wires up to 10 sq-mm. This versatility makes installation straightforward across different setups.</p><p>For those concerned about extreme weather conditions or operational environments, this SPD operates efficiently within a wide temperature range from -40&#176;C to +80&#176;C. It boasts a voltage protection level of less than or equal to 4 kV which effectively reduces transient overvoltage levels during surges.</p><p>In terms of lightning defense capabilities, it&#39;s engineered as a Type 1 Class I device with an impressive lightning current carrying capability of up to 25 kArms and a lightning impulse current capacity reaching up to 35 kA. These attributes ensure that your system remains safeguarded even during severe electrical storms or power anomalies.</p><p>This surge protection solution combines practicality with robust technical features tailored for professionals who prioritize reliability and efficiency in their electrical infrastructure projects.</p>
