<p>When it comes to safeguarding electrical systems, a reliable Surge Protection Device (SPD) is indispensable. This SPD is designed for industrial and commercial applications, offering robust protection against voltage spikes that can damage sensitive equipment. </p><p>Operating at a rated voltage of 230/400 V and a rated current of 20 kA, this device ensures your systems are shielded from unexpected surges. Its DIN Rail mounting type facilitates easy installation within control panels or distribution boards, making it convenient for integration into existing setups.</p><p>The device boasts an impressive operational temperature range from -40 to 80 degrees Celsius, ensuring functionality in diverse environmental conditions. However, it&#39;s important to note that this SPD is suitable for indoor installations only.</p><p>Speed is crucial in surge protection, and this SPD delivers with response times of less than or equal to 25 ns between Line-Neutral (L-N) and less than or equal to 100 ns between Neutral-Protective Earth (N-PE). This rapid response helps prevent potential downtime by swiftly clamping overvoltages before they can cause harm.</p><p>With four poles available, the device provides comprehensive coverage across multiple circuits. It also features an interrupt rating of 125 A, indicating its capability to handle significant fault currents without compromising performance.</p><p>Flexibility in wiring is another advantage of this SPD. It accommodates various conductor cross sections: 2.5 sq-mm for compact connections, up to 25 sq-mm for more substantial requirements, and an intermediate option at 16 sq-mm.</p><p>The voltage protection level stands at less than or equal to 1.5 kV—an assurance that even during severe surges the residual voltage remains within safe limits for connected equipment.</p><p>Classified as Type 2/Class II according to industry standards, this SPD offers mid-level protection ideal for downstream devices after primary surge arresters have already mitigated major disturbances.</p><p>In summary this surge protection device combines efficiency reliability and adaptability making it a sound choice for professionals seeking dependable electrical system safeguards in their operations</p>
