NFD04.1-440-120

NFD04.1-440-120, Bosch Rexroth Indramat, NFD Mains Filters embeds a robust Line 04 topology to suppress high-frequency noise and protect downstream drive controllers. This mains filter accepts a Nominal Voltage range of AC 115 to 440 V, delivering a continuous Rated Current of 120 A with minimal insertion loss. Housed in an IP20 Protection Class enclosure, it deflects solid contaminants larger than 12 mm while allowing natural convection. Designed for streamlined integration, the filter combines seamlessly with Rexroth Indramat shielded motor feedback cables to safeguard power electronics from regenerative spikes.

In applications demanding precise footprint control, the unit measures 100 mm length x 240 mm width x 160 mm thickness and weighs just 4.7 kg, optimizing cabinet density without sacrificing performance. Its natural convection cooling handles internal heat generation efficiently, eliminating moving parts and downtime associated with fan maintenance. Certified for operation up to 1000 m installation altitude, it remains stable under varying atmospheric pressure and avoids output derating. Mounting is tool-free on a DIN rail or panel, and the rugged housing resists mechanical stress common in industrial installations.

Integration into drive systems yields extended equipment life and reduced electromagnetic interference, helping engineers meet stringent EMC directives. The NFD04.1-440-120 ensures reliable handling of excess energy during motor deceleration, preventing voltage spikes from feeding back into controllers. Its compact form factor and industry-standard interfaces make it ideal for retrofit and new-build projects where uptime and compliance are paramount. Please respond in JSON format.
