<p>When it comes to safeguarding your electrical systems, a reliable Surge Protection Device (SPD) is essential. This SPD is engineered for industrial and commercial applications, offering robust protection without compromising on practicality or ease of installation.</p><p>Designed with a rated voltage of 35 VDC, this device efficiently handles surges with a rated current capacity of 1 kA per line and a total of 2 kA. Its compact dimensions—27 mm in width, 90 mm in height, and 65 mm in depth—make it easy to integrate into existing setups. The yellow thermoplastic casing not only provides durability but also ensures visibility within any installation environment.</p><p>This SPD boasts an IP20 degree of protection, making it suitable for indoor use where solid object ingress needs to be minimized. It mounts seamlessly onto a standard 35 mm DIN rail, facilitating straightforward installation and maintenance. With an operational temperature range from -40 to 80 degrees Celsius, it performs reliably under various environmental conditions.</p><p>Conforming to IEC 61643-21 and EN 61643-21 standards, this SPD meets stringent safety and performance criteria required by the industry. The device&#39;s weight is just under 0.1 kg at precisely 0.097 kg, ensuring that it does not add unnecessary load to your setup while maintaining structural integrity.</p><p>The tightening torque requirement is set at 0.8 N-m, supporting secure connections without over-tightening risks. It accommodates cross-sections from 0.5-6 sq-mm for solid conductors and from 0.5-4 sq-mm for flexible conductors, providing versatility across different wiring configurations.</p><p>Capacitance levels are maintained at &lt;=7 nF between lines (L-L) and &lt;=1.5 nF between line-to-protective ground (Line-PG), optimizing the balance between protection level and signal integrity.</p><p>For voltage protection levels: expect up to &lt;=70V L-L for In C2 scenarios; &lt;=500V Line-PG for In C2; &lt;=50V L-L at rapid transient conditions like those seen at a rate of change of voltage of up to 1 kV/&#181;s C3; and &lt;=450V Line-PG under similar fast-transient conditions.</p><p>Classified as a Type 3 SPD, it&#39;s designed specifically for end-stage equipment protection against residual surges not eliminated by upstream devices in the surge protective chain.</p><p>In summary, this surge protector combines effective performance metrics with user-friendly design features tailored to meet rigorous industrial demands while being straightforward enough for commercial applications as well.</p>
