Description

<p>When considering the protection of your electrical infrastructure, selecting a reliable Surge Protection Device (SPD) is crucial. This SPD is designed to safeguard your systems from voltage spikes and transients, ensuring operational continuity and safety in both industrial and commercial settings.</p><p>Rated for a nominal voltage of 230 V, this device can handle a robust current surge of up to 20 kA. Its design complies with KEMA standards, providing assurance that it meets rigorous safety and performance criteria. The unit offers a degree of protection at IP20, making it suitable for indoor applications where dust ingress is minimal but still needs consideration.</p><p>Installation is straightforward with its 35 mm DIN rail mounting system. Measuring 36 mm in width, 90 mm in height, and 66 mm in depth, it fits comfortably within standard electrical enclosures without demanding excessive space. Weighing just 232 g, it&amp;#39;s lightweight yet structurally sound due to its thermoplastic construction which also contributes to its durability under varying environmental conditions.</p><p>The operational temperature range spans from an impressive -40&amp;#176;C to +80&amp;#176;C. This wide range ensures reliability across diverse climates found throughout Australia—from the cooler southern regions to the hot northern territories—without compromising on performance.</p><p>In terms of response time, this SPD reacts swiftly with less than or equal to 25 nanoseconds between line-to-neutral (L-N) connections and less than or equal to 100 nanoseconds between neutral-to-protective earth (N-PE). Such rapid response times are critical for minimizing potential damage during transient events.</p><p>The interrupt rating stands at an impressive 125 A while maintaining a rated short circuit current capacity of up to 25 kA. These specifications underline the device&amp;#39;s ability to cope with significant fault currents without failure.</p><p>Regarding connection versatility, it accommodates various conductor sizes: solid/flexible wires up to 1.5 sq-mm; stranded wires up to 35 sq-mm; and flexible wires as large as 25 sq-mm. This flexibility simplifies integration into existing systems regardless of wiring configurations.</p><p>Voltage protection levels are maintained at =1.75 kV (L-N) and =1.5 kV (N-PE), effectively reducing over-voltage impact on sensitive equipment connected downstream.</p><p>Classified as Type 2/Class II SPD, it’s engineered primarily for installation downstream of main distribution boards or sub-distribution panels—ideal for secondary-level protection against indirect lightning strikes or switching operations within power networks.</p><p>This SPD combines technical robustness with practical design features aimed at professionals seeking dependable surge mitigation solutions tailored for Australian conditions without unnecessary complexity or cost overheads typically associated with high-end devices.</p>
