It provides 0.2 mH inductance per phase, sized to limit the dV/dt and peak currents from a PWM drive to the motor, protecting both the cable and the winding insulation on longer motor leads. Rated for a 400 V line and 76.5 A nominal load current (I_LN), the reactor's impedance (UK) is 33 % — meaning it drops about a third of the line voltage at rated current, which is typical for a motor-protection choke on a 3-phase drive output. The 0.2 mH value is tuned for the 8000 Hz carrier frequency; at lower switching frequencies the inductance may be insufficient to limit harmonics, so verify the drive's PWM setting against this part's 945 Hz minimum operating frequency. ## Thermal and enclosure class IP00 means the reactor is open-frame — no enclosure protection against dust or water ingress. The thermal class H (IEC 60085) winding insulation allows a 180 °C hot-spot temperature, which is standard for high-temperature reactor applications in drive cabinets with limited airflow. Total power loss at rated load is 530 W (400 W coil loss + 130 W iron core loss) at a 40 °C ambient. That heat must be dissipated within the enclosure; factor it into the cabinet's thermal budget — a 530 W continuous heat source in a sealed box will raise internal temperature significantly without forced ventilation. Termination is via flat-type connectors on the main current circuit — no screw terminals, no ring lugs. The panel builder will need to mate these with flat busbars or fork-type crimp terminals rated for the 85 A continuous path. Verify the connector dimensions against your existing busbar layout before committing the panel design.","metaTitle":"SIDAC 4EU2752-0AF40-4BA0 output reactor, 85A, 8000Hz","metaDescription":"SIDAC output reactor 4EU2752-0AF40-4BA0, 3-phase AC, 85A max, 8000Hz rated frequency, 0.2mH, IP00, thermal class H.
