The SFD3 Surge Filter is a robust solution designed for industrial and commercial applications, offering reliable protection against voltage surges. Engineered with precision, this surge filter ensures the safety of your electrical systems by mitigating the effects of transient over-voltages.
Operating at a rated voltage of 275 VAC between line and neutral (L-N) and 255 VAC between neutral and protective earth (N-PE), the SFD3 provides substantial protection with its impressive rated current capacity—50 kA for L-N connections and 60 kA for N-PE connections. This makes it an ideal choice for environments where electrical stability is paramount.
As a three-phase device, the SFD3 is equipped to handle complex electrical networks, making it suitable for diverse applications across various industries. Its degree of protection is rated at IP20, indicating that while it offers basic protection against dust ingress, it's primarily designed for indoor installations where exposure to moisture isn't a concern.
Installation is straightforward thanks to its DIN rail mounting type, which simplifies integration into existing panels or enclosures. With dimensions measuring 180 mm in width, 95 mm in height, and 69 mm in depth, this compact design doesn't compromise on performance despite its small footprint.
The operational temperature range from -40 to 70 degrees Celsius underscores its versatility in different environmental conditions—from cold storage facilities to high-temperature manufacturing plants. This broad range ensures consistent performance regardless of external temperatures.
Compliance with international standards such as IEC 61643-11, AS/NZS 1768, UL 1449, and IEEE 62.41.2 highlights the SFD3's adherence to stringent safety and performance criteria. These certifications provide peace of mind that you're investing in a product that meets global benchmarks for quality and reliability.
With three poles incorporated into its design, this surge filter efficiently manages power distribution while maintaining optimal safety levels. The voltage protection level remains below <1 kV (L-N) and <1.5 kV (N-PE), ensuring minimal risk of equipment damage during surges.
Furthermore, it boasts a lightning impulse current rating of up to 6.25 kA (L-N) and an impressive 15 kA (N-PE), showcasing its capability to withstand significant electrical disturbances without compromising functionality or safety.
In summary, the SFD3 Surge Filter delivers dependable surge protection tailored for demanding industrial settings. Its blend of technical specifications ensures comprehensive defense against power anomalies while maintaining seamless operation within your infrastructure's parameters.
