Description

<p>When it comes to safeguarding your electrical systems from unexpected surges, having a reliable Surge Protection Device (SPD) is crucial. This SPD offers robust protection for both industrial and commercial applications, ensuring that your equipment remains unharmed during voltage spikes.</p><p>Designed to handle a rated voltage of 230/400 V, this device efficiently manages surge currents with a rated current capacity of 20 kA for line-to-neutral (L-N) connections and an impressive 80 kA for neutral-to-protective earth (N-PE) connections. Its ability to handle high surge currents makes it an ideal choice for environments prone to lightning strikes or power fluctuations.</p><p>The SPD boasts an IP20 degree of protection, which ensures safety against solid objects larger than 12 mm while being mounted on a standard 35 mm DIN rail. With dimensions of 72 mm in width, 90 mm in height, and 70 mm in depth, this compact device fits seamlessly into most control panels without occupying excessive space.</p><p>Built from durable thermoplastic materials, the device is designed to withstand harsh environmental conditions with an operational temperature range from -40&amp;#176;C to +80&amp;#176;C. This wide range ensures reliability across various climates and installation scenarios.</p><p>Meeting KEMA standards and approvals underscores its quality and performance credibility. The response time is less than or equal to 100 nanoseconds, ensuring rapid reaction times when surges occur—crucial for protecting sensitive electronic components.</p><p>With four poles available, the SPD accommodates different wiring configurations. It supports cross-section conductors ranging from 1.5 sq-mm solid/flexible up to 35 sq-mm stranded cables. For flexible cables specifically, it can accommodate up to 25 sq-mm conductors.</p><p>The voltage protection level stands at less than or equal to 1.5 kV for both L-N and N-PE connections—a testament to its efficiency in maintaining safe voltage levels within protected circuits during transient events.</p><p>Additionally, the lightning current carrying capability reaches up to an impressive 100 kArms while supporting a rated short circuit current of up to 25 kA—ensuring durability even under extreme conditions.</p><p>Classified as Type 2/Class II according to international standards, this SPD provides secondary protection suitable for downstream devices after primary surge arresters have absorbed initial impacts.</p><p>Weighing just over half a kilogram at approximately452 grams,this sturdy yet lightweight device offers peace of mind without adding unnecessary load onto mounting structures.The combination of technical specifications makes this SPD not only practical but also indispensable where consistent power quality is paramount.MPN: [Manufacturer Part Number]</p>
