<p>When it comes to safeguarding your electrical systems, the SFDE Series Surge Filter offers a robust solution tailored for industrial and commercial applications. This device is designed to protect sensitive equipment from voltage spikes and surges that can occur due to lightning strikes or other electrical disturbances.</p><p>The SFDE Series operates at a rated voltage of 275 VAC between Line and Neutral (L-N) and 255 VAC between Neutral and Protective Earth (N-PE). It efficiently manages surge currents with a rated current capacity of 20 kA for L-N connections and an impressive 25 kA for N-PE connections. This capability ensures that the system can handle substantial surges, providing peace of mind in environments where power quality is critical.</p><p>One of the standout features of this surge filter is its low Voltage Protection Level, which is less than 0.6 kA for L-N configurations. This means that even during significant surges, the voltage let-through remains minimal, protecting connected devices from potential damage.</p><p>The SFDE Series also boasts a Lightning Impulse Current rating of 2 kA on the N-PE path. This feature provides an additional layer of protection against high-energy transients typically associated with lightning events.</p><p>Designed for single-phase applications, this surge filter integrates seamlessly into existing electrical infrastructure without requiring extensive modifications. Its compact design makes it suitable for installations where space may be limited while still delivering reliable performance.</p><p>In summary, the SFDE Series Surge Filter combines advanced protection capabilities with practical design considerations, making it an excellent choice for those looking to enhance their system&#39;s resilience against power disturbances.</p>
