{"product_id":"hnf011a-f240-e0202","title":"HNF01.1A-F240-E0202","description":"\u003cp\u003eBosch Rexroth Indramat manufactures the \u003cstrong\u003eHNF01.1A-F240-E0202\u003c\/strong\u003e mains filter, a line component in the HNF Mains Filters series used in drive packages for industrial automation. The filter sits on the input side of a multi-axis converter rack and blocks high-frequency noise from returning to the facility power bus. By stabilizing the supply, it helps keep sensitive sensors, PLCs, and neighboring machines within electromagnetic emission limits while delivering the required current to the drives. This placement also reduces conducted interference before it reaches the plant supply and supports reliable operation of connected converter assemblies. Because it works as a passive input component, it conditions the incoming line without interrupting normal power delivery to the drive group.\u003c\/p\u003e\u003cp\u003eThe filter is sized for drive groups with \u003cstrong\u003e6 axes\u003c\/strong\u003e, so one housing can serve an entire machining or handling station under one protective earth connection. It tolerates a cumulative motor cable length of \u003cstrong\u003e240 m\u003c\/strong\u003e, which suits distributed servo layouts without exceeding common-mode voltage thresholds. With a nominal current rating of \u003cstrong\u003e202 A\u003c\/strong\u003e, it carries the phase current required by large converter stacks. Its electromagnetic behavior is rated \u003cstrong\u003eC3\u003c\/strong\u003e, and this category follows the limits set by \u003cstrong\u003eDIN EN 61800-3\u003c\/strong\u003e for industrial areas without public access. The inductive and capacitive elements balance attenuation with thermal dissipation so the filter can operate continuously at the stated current.\u003c\/p\u003e\u003cp\u003eThe filter is \u003cstrong\u003edesign version 1\u003c\/strong\u003e and belongs to \u003cstrong\u003eseries 01\u003c\/strong\u003e. The circuit is intended \u003cstrong\u003efor feeding devices only\u003c\/strong\u003e, so it must be connected ahead of the converters rather than downstream toward the motors. This topology helps maintain the leakage current profile needed for reliable ground-fault monitoring. Input-side installation keeps the filter between the incoming supply and the converter rack, where it can suppress conducted emissions before they spread through the cabinet wiring. The housing arrangement also supports a straightforward grounding path, which is important for stable filter performance in multi-axis systems. \u003cstrong\u003eWiring diagrams and mounting points\u003c\/strong\u003e support cabinet installation and proper placement on the converter input side.\u003c\/p\u003e","brand":"Bosch Rexroth Indramat","offers":[{"title":"Unstocked","offer_id":52082359009581,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/hnf011a-f240-e0202__2fdf0922-4525-435f-99ea-80b9fa72cf45.webp?v=1778570179","url":"https:\/\/servosupplier.com\/products\/hnf011a-f240-e0202","provider":"Servo Supplier","version":"1.0","type":"link"}
