<p>When it comes to safeguarding your electrical systems, the right surge protection device (SPD) can make all the difference. This SPD is designed specifically for indoor installations, offering reliable performance in environments where voltage spikes are a concern. Let&#39;s delve into its technical specifications to see if it aligns with your needs.</p><p>This single-phase SPD is rated at 120 V, making it suitable for various commercial and industrial applications. It boasts a rated current of 2 kA, providing robust protection against transient overvoltages that could otherwise disrupt operations or damage sensitive equipment.</p><p>Installation is straightforward thanks to its DIN rail mounting type, which ensures a secure fit in standard electrical panels. The operational temperature range of -40 to 80 degrees Celsius means this device can withstand extreme conditions without compromising performance—ideal for diverse Australian climates.</p><p>Response time is crucial in surge protection, and this device excels with an impressive response time of less than or equal to 25 nanoseconds for line-to-neutral connections and up to 100 nanoseconds for line/neutral-to-protective earth (L/N-PE). This rapid response helps prevent potential damage from surges by clamping voltages swiftly.</p><p>The interrupt rating stands at 25 A, ensuring that the device can handle significant fault currents effectively. It&#39;s also designed with flexibility in mind regarding wiring options: accommodating cross sections of 0.5 sq-mm solid/flexible conductors, up to 4 sq-mm stranded conductors, and 2.5 sq-mm flexible conductors.</p><p>Voltage protection levels are another critical consideration; this SPD offers levels of less than or equal to 0.64 kV for standard connections and up to 0.8 kV when considering L/N-PE configurations. These figures indicate how well the device limits residual voltage during surges—essentially keeping downstream equipment safe from excessive voltage exposure.</p><p>Classified as Type 3/Class III according to international standards, this SPD is designed primarily for fine protection within distribution boards or close proximity applications where precise control over transient voltages is necessary.</p><p>In summary, this Surge Protection Device combines efficiency with reliability—a practical choice for professionals seeking dependable performance under demanding conditions while maintaining ease of installation and operation indoors.</p>
