Description

<p>In the realm of industrial and commercial electrical systems, ensuring protection against voltage surges is critical. This Surge Protection Device (SPD) stands as a reliable choice for safeguarding your equipment from transient over-voltages caused by lightning strikes or electrical faults. Engineered to meet the demands of modern infrastructure, this SPD offers robust performance wrapped in a compact design.</p><p>Operating at a rated voltage of 230/400 V and handling a rated current of 20 kA, it provides substantial protection across various applications. Its Type 2, Class II classification ensures that it is suitable for installation downstream from main distribution boards, offering secondary protection in coordination with upstream SPDs.</p><p>The device&amp;#39;s physical dimensions are designed for convenience and efficiency in space utilization—measuring 72 mm wide, 90 mm high, and 66 mm deep. It mounts easily onto a standard 35 mm DIN rail, making installation straightforward in common electrical panels.</p><p>Durability is assured with an operational temperature range extending from -40 to 80 degrees Celsius. The degree of protection is rated at IP20, indicating its suitability for indoor use while being protected against solid objects greater than 12 mm but not water-resistant.</p><p>The SPD features fast response times—less than or equal to 25 nanoseconds between line and neutral (L-N), and less than or equal to 100 nanoseconds between neutral and protective earth (N-PE)—ensuring rapid action when surges occur. Additionally, it boasts an interrupt rating of up to 125 A.</p><p>For safety compliance and peace of mind, the device meets KEMA standards—a testament to its reliability under rigorous testing conditions. The material construction consists of durable thermoplastic weighing approximately 416 grams.</p><p>Connection versatility is provided through cross-section capabilities: accommodating up to a solid/flexible conductor size of 1.5 sq-mm; stranded conductors up to 35 sq-mm; and flexible conductors up to 25 sq-mm. This flexibility facilitates integration into various system configurations without complications.</p><p>Voltage protection levels are kept impressively low at less than or equal to 1.5 kV both L-N and N-PE—ensuring minimal residual voltage during operation which helps protect sensitive equipment connected downstream.</p><p>This surge protector also supports a rated short circuit current capacity reaching up to an impressive threshold of 25 kA—demonstrating its capability in managing extreme fault conditions effectively without compromising on performance integrity over time.</p><p>Overall this SPD combines technical excellence with practical application benefits making it an ideal choice for professionals seeking dependable surge mitigation solutions within their electrical installations.</p>
