This compact unit features a \u003cstrong\u003eNominal Current: 30 A\u003c\/strong\u003e rating and operates at \u003cstrong\u003e480 VAC\u003c\/strong\u003e, making it suitable for three-phase industrial power environments. With a \u003cstrong\u003eWeight: 1.2 kg\u003c\/strong\u003e profile and an overall footprint defined by \u003cstrong\u003eDimension A: 270 mm\u003c\/strong\u003e, \u003cstrong\u003eDimension B: 50 mm\u003c\/strong\u003e, and \u003cstrong\u003eDimension C: 85 mm\u003c\/strong\u003e, the filter balances space efficiency with robust construction. Mechanical attachment is ensured via \u003cstrong\u003eBolt: M5, 2.2 Nm\u003c\/strong\u003e, while its \u003cstrong\u003eTerminals: 10 mm², 1.9…2.2 Nm\u003c\/strong\u003e torque rating supports secure electrical connections. Specified for a \u003cstrong\u003eTemperature: 50°C environment\u003c\/strong\u003e, the 3NF-30 filter adheres to stringent thermal requirements early in the installation phase.\u003c\/p\u003e\n\n\u003cp\u003eOptimized to reduce harmonic distortion and ground leakage currents, the 3NF-30 employs a \u003cstrong\u003ethree-phase filter\u003c\/strong\u003e topology that attenuates both common-mode and differential-mode noise. The device maintains \u003cstrong\u003elow leakage current\u003c\/strong\u003e characteristics while reliably handling peak loads from connected servo amplifiers in the AKD product family. Internally, the filter protects downstream electronics by isolating high-frequency noise, and its \u003cstrong\u003elive power terminals\u003c\/strong\u003e remain energized for up to ten minutes after mains disconnection, emphasizing the need for compliance with safety procedures. Dimensional details such as \u003cstrong\u003eDimension D: 240 mm\u003c\/strong\u003e, \u003cstrong\u003eDimension F: 255 mm\u003c\/strong\u003e, and \u003cstrong\u003eDimension G: 30 mm\u003c\/strong\u003e allow precise panel integration, while \u003cstrong\u003eDimension M: 5.4 mm\u003c\/strong\u003e and \u003cstrong\u003eDimension P: 260 mm\u003c\/strong\u003e ensure standardized mounting clearances in control cabinets. The IP20 protection rating further requires installation within a dedicated enclosure to prevent ingress and maintain performance integrity.\u003c\/p\u003e\n\n\u003cp\u003eBuilt for rigorous industrial automation environments, the 3NF-30 mains filter offers dependable reliability over extended service cycles. Its robust design mitigates electromagnetic interference without compromising efficiency, minimizing energy loss in critical motion control applications. Integration with Kollmorgen’s AKD drive series is seamless, with connection diagrams provided to guide correct wiring and grounding. Fixed mounting requirements and clear de-energization procedures support safe handling and maintenance, while the broad operating temperature range up to 50°C ensures suitability for diverse factory conditions. Ideal for servo systems, process automation, and precision machinery, the 3NF-30 delivers consistent EMI suppression where uninterrupted operation is paramount.\u003c\/p\u003e","brand":"Kollmorgen","offers":[{"title":"Unstocked","offer_id":51789809877293,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/Mains_Filter_Series__46507992-88c5-47c4-92ff-c9e15675aedc.webp?v=1760125196","url":"https:\/\/servosupplier.com\/products\/3nf-30","provider":"Servo Supplier","version":"1.0","type":"link"}
