It sits between the drive output and the motor cable to limit the rate of voltage rise (dV/dt) and reduce reflected-wave peaks on long cable runs — a standard mitigation for motor insulation stress in variable-frequency drive installations. For a drive application, size the reactor so the motor's full-load current does not exceed this figure; a 78A reactor typically pairs with a drive rated around 55–75 kW at 400 V, depending on the load profile. The 0.15 mH inductance sets the dV/dt limiting characteristic; lower inductance values give less filtering but also lower voltage drop and heat dissipation. The 60 Hz minimum operating frequency and 0 Hz rated value indicate it is designed for the output of a PWM drive where the fundamental frequency can be as low as 0 Hz (DC braking or holding), not a line-frequency choke. The flat-type terminals accept busbar or cable lugs; plan for adequate bending radius and clearance around the 0.27 m width. Thermal class H insulation allows a 180 °C hot-spot temperature, so adjacent components should be spaced to avoid heat soak. Mounting orientation should allow natural convection; forced airflow is recommended if the cabinet ambient exceeds 40 °C.","metaTitle":"Siemens SIDAC 4EU2752-0EQ00-0BA0 Output Reactor, 78A, 3-Phas","metaDescription":"Siemens SIDAC 4EU2752-0EQ00-0BA0 output reactor, 3-phase, 78A max, 400V AC, 0.15mH, IP00, thermal class H, mature lifecycle.
