<p>When it comes to safeguarding your industrial or commercial operations from electrical surges, having a reliable surge protection device is crucial. This particular Surge Protection Device (SPD) provides robust protection with its impressive specifications tailored for demanding environments.</p><p>Designed for 3-phase systems, this SPD operates effectively at a rated voltage of 400 VAC and can handle a substantial rated current of 50 kA (L-PE). Its rapid response time of less than 5 nanoseconds ensures that your equipment is shielded almost instantaneously from transient overvoltages.</p><p>The device&#39;s LED display provides clear indications of power status and thermal failures, allowing for easy monitoring without the need for additional tools. With shunt connection type and mounted on a TS35 DIN rail, installation is straightforward and compatible with standard electrical setups.</p><p>Measuring 54 mm in width, 70 mm in height, and 95 mm in depth, this SPD fits snugly into compact spaces while maintaining high performance. The aluminium construction not only contributes to its durability but also keeps the weight manageable at just 400 grams. </p><p>This SPD meets several international standards including IEC 61643-11:2011, AS/NZS 1768:2007, IEEE 62.41.2:2002, and UL 1449 (3rd Edition), ensuring compliance with global safety benchmarks. It offers an IP20 degree of protection suitable for indoor use where there’s no exposure to dust or water ingress beyond basic levels.</p><p>In terms of operational resilience, it performs reliably within temperatures ranging from -40&#176;C to +70&#176;C and humidity levels between 5% to 95%. This makes it ideal for diverse climatic conditions across Australia.</p><p>The voltage protection level is maintained below &lt;800 V which helps in minimizing potential damage during overvoltage events. Additionally, it supports modes of protection like L-L and L-PE to cover various surge scenarios effectively.</p><p>For maintenance personnel ease-of-use, the tightening torque is set at a practical value of 2 N-m ensuring secure connections without excessive force requirements. Moreover, the fuse rating stands at a competent level of 32 A supporting overall circuit integrity during fault conditions.</p><p>With lightning impulse current capability reaching up to 6.25 kA (L-PE) and rated short circuit current standing at an impressive figure of up to 25 kA; this SPD assures comprehensive protective measures against severe electrical disturbances that could otherwise jeopardize sensitive equipment or disrupt operations significantly.</p><p>In summary, this Surge Protection Device combines advanced technology with practical design features making it an essential component for any infrastructure needing dependable surge mitigation solutions under varied environmental conditions.</p>
