The Bosch Rexroth Indramat HNF01.1A-M750-R0300-A-480-NNIT from the HNF Mains Filters series is a high-performance HNF01.1A-M750-R0300-A-480-NNIT mains filter designed for demanding industrial environments. Its compact design handles a Mains Connecting Voltage of AC 400-480 V and sustains a Nominal Current of 300 A with ease. Certified for Industrial Area use under EMC Area Per DIN EN standards, it caters specifically to advanced drive and regenerative power systems. The filter’s robust Supply System supports Regenerative Units only, ensuring precise suppression of electromagnetic disturbances while maintaining power integrity.
Engineered for seamless integration, the filter features an optimized impedance network that meets strict conformity levels of DIN EN without additional external components. Its built-in Supply Unit architecture minimizes cabling effort and reduces panel space requirements. The design’s front-mount terminals permit straightforward wiring of three-phase mains at both 400 V and 480 V, and the unit’s thermal rating allows continuous operation at full load without derating. Maintenance is simplified through a modular housing that provides visual indication of filter health and easy access for service checks.
In application, the HNF01.1A-M750-R0300-A-480-NNIT excels in machine tool installations, conveyor systems, and regenerative braking setups where compliance with EMC directives is critical. Its precise attenuation characteristics protect sensitive inverters, PLCs, and servo drives from common-mode and differential-mode noise. With this filter in place, facilities achieve optimized energy efficiency, reduced downtime, and enhanced system reliability.
