HMF01.1N-N0K1-M0320-N-690-NNNN

The Bosch Rexroth Indramat HMF01.1N-N0K1-M0320-N-690-NNNN from the HMF Motor Filters series delivers robust interference suppression with a Rated Current of 320 A and a power output of 1 kW. This Dv/dt Filter with Limiter is designed for direct connection to a 3-phase 690 V AC supply and uses natural convection cooling to maintain optimal thermal performance. Featuring a Free Installation design, the filter supports flexible placement inside IP54 cabinets while its IP00 protection class enclosure safeguards internal components before cabinet mounting. High-frequency voltage spikes and leakage currents are effectively attenuated to extend the lifetime of motor bearings and drive controllers.

Installation is straightforward: three single-phase chokes must be attached one per motor phase, and the device is mounted in a vertical orientation to ensure proper airflow. Maintain at least a 50 mm clearance at the sides and 100 mm at the top to avoid heat buildup. The module operates reliably across an ambient temperature range of -10 to +50 °C and an operating frequency band of 0–100 Hz. Compliance with prescribed environmental and mounting conditions ensures consistent performance without derating.

Engineers will appreciate the compact yet durable construction, which simplifies cabinet layouts and maintenance procedures. The filter’s ability to reduce transient overvoltages and current leakage enhances drive stability and minimizes electromagnetic interference in precision automation systems. Backed by Rexroth Indramat quality, the HMF01.1N-N0K1-M0320-N-690-NNNN is an essential component for modern motor-driven applications, offering reliable protection and long service life.
