Its 0.0041 H inductance and 5.67% relative throttling factor are sized to limit harmonic distortion and reduce voltage notching on the drive input. ## Mounting and integration constraints At 0.178 m wide, 0.153 m tall, and 0.12 m deep, this reactor occupies a footprint roughly the size of a standard contactor but with more depth allowance for the core and winding overhang. ## Reactive power and filter bank application The filter bank's rated reactive power is 7 500 var (7.5 kvar), which places this reactor in the range used for small to medium drives — typically 5.5 to 11 kW motors depending on the drive's DC-link configuration and the desired harmonic mitigation level. The 5.67% impedance is a common value for line reactors in IEC markets; it provides enough inductance to limit inrush current and reduce harmonic current draw without causing excessive voltage drop under full load. For applications requiring tighter harmonic control (IEEE 519 compliance), a higher-impedance reactor or a passive filter stage would be needed downstream.","metaTitle":"Siemens SIDAC 4EP3801-0MS00 Filter Reactor, 400V 11.8A 5.67%","metaDescription":"Siemens SIDAC 4EP3801-0MS00 3-phase filter reactor, 400V AC, 11.8A rated, 5.67% throttling, 210Hz resonant frequency.
