<p>When it comes to safeguarding your photovoltaic (PV) systems, a reliable surge protection device is essential. This Surge Protection Device (SPD) is designed with precision to ensure optimal performance and durability in industrial and commercial environments. Featuring a rated current of 40 kA, this SPD effectively mitigates the impact of electrical surges, providing peace of mind for installations up to 1500 VDC PV systems.</p><p>Built with thermoplastic material, this SPD offers robust protection while maintaining a compact design. It fits seamlessly into existing setups with its standard 35 mm DIN rail mounting type. The dimensions—72 mm in width, 90 mm in height, and 73 mm in depth—ensure that it occupies minimal space without compromising on functionality.</p><p>The SPD&#39;s degree of protection is rated at IP20, making it suitable for indoor applications where contact with fingers or similar objects needs to be prevented but not against water ingress. With a response time of less than or equal to 25 nanoseconds, this device reacts swiftly to voltage spikes, minimizing potential damage.</p><p>For ease of installation and compatibility with various wiring configurations, the SPD accommodates cross sections ranging from 1.5 sq-mm solid/flexible wires up to 35 sq-mm stranded wires and 25 sq-mm flexible wires. This versatility ensures that the device can be integrated into diverse setups without requiring extensive modifications.</p><p>Safety and compliance are paramount; hence this SPD adheres to KEMA and UL standards and approvals. These certifications underscore its reliability and suitability for demanding applications across different sectors.</p><p>Weighing in at just 562 grams, the device manages an impressive balance between sturdiness and lightweight construction. Its ability to handle a rated short circuit current of up to 10 kA further attests to its capability under challenging conditions.</p><p>Moreover, the voltage protection level is maintained below &lt;4.5 kV ((DC+/DC-) -&gt; PE)), ensuring that even during significant surges your equipment remains safeguarded from excessive voltages which could otherwise lead to costly damages or downtimes.</p><p>In summary, if you&#39;re looking for an efficient solution that combines safety compliance with effective surge mitigation for high-voltage DC systems like PV installations—this Surge Protection Device stands out as an ideal choice thanks to its comprehensive features tailored towards protecting your investments efficiently over time.</p>
