<p>When selecting a surge protection device for industrial and commercial applications, technical requirements are paramount. This particular Surge Protection Device (SPD) is engineered to meet rigorous demands with its robust specifications.</p><p>Designed for environments where reliability is critical, this SPD boasts a rated voltage of 690 V and can handle a rated current of 25 kA. It offers an impressive lightning current carrying capability of 25 kArms and lightning impulse current rating also at 25 kA. These features ensure that your equipment remains safeguarded against unexpected power surges.</p><p>The SPD&#39;s dimensions—36 mm in width, 150 mm in height, and 73 mm in depth—are compact enough for easy integration into existing systems without compromising on performance. Weighing in at 507 g, it strikes a balance between sturdiness and ease of installation.</p><p>Built from durable thermoplastic material, the device provides reliable protection with an IP20 degree of protection, indicating its resistance to solid objects larger than 12.5 mm but not water-resistant. Its operational temperature range spans from -40 to 80 degrees Celsius, making it suitable for various climatic conditions across Australia.</p><p>This SPD conforms to UL and CSA standards, ensuring compliance with international safety regulations—a crucial factor for any project requiring stringent adherence to quality benchmarks.</p><p>In terms of electrical characteristics, the voltage protection level is maintained at &lt;=4 kV while offering a response time of &lt;=100 ns. Such swift responsiveness minimizes downtime by quickly mitigating transient overvoltage conditions before they impact sensitive equipment.</p><p>For installation flexibility, the device supports cross-sections up to 50 sq-mm stranded or downscaled options like 35 sq-mm flexible/stranded or even as low as 25 sq-mm flexible wiring configurations. The fuse rating stands at an ample 125 A which complements its high-performance metrics effectively.</p><p>Classified as Type 1/Class I SPD classifies it well-suited for locations prone to direct lightning strikes or high exposure risks; thus providing peace-of-mind knowing your infrastructure remains protected under extreme circumstances when nature unleashes her fury unpredictably upon electrical networks nationwide!</p><p>This surge protector represents both practicality &amp; efficiency combined seamlessly within one product package catering specifically towards those seeking dependable solutions amidst ever-evolving technological landscapes today!</p>
