Description

<p>When considering the protection of your electrical systems, especially in industrial and commercial settings, a reliable surge protection device (SPD) is crucial. This SPD is designed to safeguard sensitive equipment from voltage spikes and transients, ensuring operational continuity and safety.</p><p>With a rated voltage of 230 V, this single-phase device provides robust performance suitable for a wide range of applications. It&amp;#39;s built to withstand the harshest environments with an operational temperature range from -40 to 80 degrees Celsius, making it ideal for use across various climatic conditions found in Australia.</p><p>The SPD&amp;#39;s construction features thermoplastic material known for its durability and resistance to heat, contributing to the product’s longevity. It offers a degree of protection at IP20, which means it&amp;#39;s protected against solid objects over 12 mm but not against water ingress. This makes it best suited for indoor installations where moisture exposure is minimal.</p><p>Installation is straightforward with its 35 mm DIN rail mounting type. The compact dimensions—36 mm in width, 90 mm in height, and 73 mm in depth—ensure that it fits neatly into existing setups without requiring extensive space adjustments. Weighing just 340 grams, handling during installation or maintenance is manageable without extra effort.</p><p>This SPD complies with several standards and approvals including VDE, KEMA, and UL certifications. These endorsements attest to its reliability and adherence to international safety standards.</p><p>One of the standout features is its response time of less than or equal to 100 nanoseconds (ns), providing almost instantaneous protection when surges occur. The fuse rating stands at 125 A offering adequate safeguarding capacity before tripping occurs under fault conditions.</p><p>In terms of current carrying capability during lightning events—a critical factor in regions prone to such occurrences—the device can handle up to 50 kArms lightning current carrying capability along with a lightning impulse current rating also at 50 kA. This ensures that even significant surges are effectively managed without compromising system integrity.</p><p>The cross-sectional area accommodates various wire types: up to 50 sq-mm stranded conductors or flexible wires ranging from 25 sq-mm upwards depending on specific needs during installation.</p><p>Lastly, as a Type 1 Class I SPD with a voltage protection level capped at &amp;lt;=2.5 kV this unit offers primary surge protection suitable for direct lightning strikes or high-energy disturbances typically encountered near service entrances or main distribution boards within facilities requiring enhanced protective measures against severe overvoltage events.</p>
