<p>When selecting a surge protection device for your industrial or commercial setup, the technical specifications and reliability of the product are paramount. This device offers robust protection, designed specifically to safeguard up to 1200 VDC photovoltaic (PV) systems. With a rated current of 40 kA, it provides substantial defense against electrical surges that could potentially damage equipment.</p><p>Constructed from durable thermoplastic material, this surge protector is built to withstand demanding environments while maintaining an IP20 degree of protection. This ensures safety against solid objects over 12 mm in size but does not provide water resistance, making it ideal for indoor applications.</p><p>The compact design allows for easy installation on a standard 35 mm DIN rail with dimensions measuring at 72 mm in width, 90 mm in height, and 73 mm in depth. Despite its sturdy build weighing in at just 509 grams, it fits seamlessly into most electrical panels without adding significant bulk.</p><p>This device meets rigorous standards and approvals including KEMA and UL certifications, underscoring its reliability and performance in critical applications. The response time is impressively fast at less than or equal to 25 nanoseconds (ns), ensuring quick action against transient voltage spikes.</p><p>With a voltage protection level under &lt;3.8 kV ((DC+/DC-) -&gt; PE)), this surge protector effectively limits overvoltage conditions to safe levels across circuits. It supports various wire cross sections: from as small as 1.5 sq-mm solid/flexible wires up to larger configurations like 35 sq-mm stranded or 25 sq-mm flexible wires—making it versatile for different wiring setups.</p><p>Additionally, the rated short circuit current stands at an adequate capacity of 10 kA which contributes further towards safeguarding your system against unexpected electrical faults.</p><p>In summary, this surge protection device is a well-rounded choice for those seeking reliability and performance within their PV systems without compromising on space or quality standards.</p>
