<p>When it comes to safeguarding your electrical systems from unpredictable power surges, the SFD3 Surge Filter is a reliable choice for both industrial and commercial applications. Designed with precision, this robust device ensures that your equipment remains protected against voltage spikes, which can otherwise lead to costly downtime or damage.</p><p>Let&#39;s delve into the technical specifics. The SFD3 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 handles a rated current of up to 50 kA (L-N) and 60 kA (N-PE), making it well-suited for high-demand environments.</p><p>This three-phase surge filter is engineered with an IP20 degree of protection, ensuring basic safety against dust ingress while being mounted on a DIN rail for easy integration into existing setups. Its compact dimensions—measuring 95 mm in length, 180 mm in width, and 69 mm in height—allow it to fit seamlessly into most control panels without consuming excessive space.</p><p>One of the standout features of the SFD3 is its wide operational temperature range from -40&#176;C to 70&#176;C. This adaptability makes it ideal for use in various climates across Australia, from chilly southern regions to the hot northern territories.</p><p>In terms of compliance, this surge filter meets several key standards: IEC 61643-11 outlines its performance requirements; AS/NZS 1768 ensures adherence to local lightning protection standards; UL 1449 provides assurance regarding safety; and IEEE 62.41.2 offers guidelines on recommended practices for surge voltages in low-voltage AC power circuits.</p><p>Weighing just 1.5 kg, the SFD3 is lightweight yet durable enough to withstand demanding conditions. Its voltage protection level stands at less than 1 kV (L-N) and less than 1.5 kV (N-PE), providing peace of mind by minimizing potential overvoltage exposure.</p><p>Additionally, it&#39;s capable of handling lightning impulse currents up to an impressive rate—6.25 kA (L-N) and a substantial 15 kA (N-PE). This capacity further underscores its suitability for areas prone to frequent thunderstorms or electrical disturbances.</p><p>The product&#39;s rated short circuit current is set at 32 A, ensuring that even during unexpected events like short circuits or overloads, your system remains safeguarded effectively without compromising performance integrity.</p><p>Overall, if you&#39;re seeking an efficient solution tailored towards enhancing system resilience against electrical surges while maintaining compliance with industry standards—the SFD3 series delivers precisely what you need within those parameters confidently meeting technical requirements comprehensively aligned towards optimal operational continuity across diverse settings throughout Australia seamlessly integrated via Manufacturer Part Number: SFD3</p>
