<p>When it comes to safeguarding your electrical systems, the SDN Series Surge Protection Device (SPD) offers a robust solution tailored for industrial and commercial applications. Designed with precision, this SPD ensures reliability and efficiency in protecting sensitive equipment from voltage spikes.</p><p>Operating at a rated voltage of 275 VAC between Line and Neutral (L-N), and 255 VAC between Neutral and Protective Earth (N-PE), this device is engineered to handle substantial current loads. With an impressive rated current capacity of 100 kA for L-N connections and 60 kA for N-PE, it effectively mitigates the risks associated with power surges.</p><p>The device is designed for three-phase systems, making it suitable for complex installations requiring comprehensive protection across multiple lines. Its shunt connection type allows seamless integration into existing setups without significant modifications. The DIN rail mounting facilitates straightforward installation, ensuring that the SPD can be securely positioned within control panels or distribution boards.</p><p>With dimensions of 141 mm in length, 80 mm in width, and 69 mm in height, the compact design does not compromise on performance while fitting comfortably into space-constrained environments. Weighing just 730 grams, it is easy to handle during installation or maintenance procedures.</p><p>This surge protection device boasts a degree of protection rated at IP20, providing adequate resistance against solid objects while being intended for indoor use where moisture exposure is minimal. It operates efficiently across a broad temperature range from -40&#176;C to +70&#176;C, making it versatile enough to function under extreme environmental conditions typical in various industrial settings.</p><p>Adhering to international standards like IEC 61643-11, AS/NZS 1768 as well as UL 1449 and IEEE 62.41.2 certifications underscores its credibility in delivering safety and compliance across different regions including Australia.</p><p>For those concerned about lightning-induced surges, this SPD offers additional peace of mind with its lightning impulse current ratings of up to 15 kA alongside a voltage protection level set at an efficient threshold of just over one kiloampere (1.4 kA L-N).</p><p>Overall whether you are upgrading an existing system or planning new installations choosing the SDN Series Surge Protection Device promises robust defense against unpredictable electrical disturbances ensuring longevity operational stability &amp; reduced downtime risks associated with power quality issues common within demanding environments today</p>
