The R911335903 (HNL01.2E-0400-N0051-A-480-NNNN) is a Bosch Rexroth mains choke engineered for applications with multiple transducers in proximity. It attenuates capacitor overload during cosine correction and limits mains voltage dips from commutation events. Rated at 51A, it features three inductors with 400μH each, operates at 50/60Hz, and has a protection type of IP10. The device weighs 13.5kg, supports flexible mounting orientation, and is intended for rectifier-based supply systems. It provides overvoltage protection, minimizes line current harmonics, and mitigates semiconductor loads. Proper installation procedures must be observed.
