It's designed to sit between a variable-frequency drive and the motor, smoothing the PWM waveform to reduce voltage spikes and limit capacitive charging currents in long cable runs. The 0.3 mH inductance and 59% impedance (UK) are sized for motor cables typically up to 100–200 m, depending on the drive's carrier frequency and cable capacitance. Thermal class H insulation (180 °C rated) means the reactor can handle the elevated core temperatures from the 260 W iron loss plus 300 W coil loss at full load without derating prematurely. The 120 A maximum current is the thermal limit at 40 °C ambient. If your drive's rated output current is 108 A (the I_LN value in the description string), that's the continuous RMS current the reactor is designed for at the 3.6 kHz switching frequency — the 120 A figure gives headroom for overloads and harmonics. The 3.6 kHz switching frequency matches many IGBT-based drives operating in the 3–4 kHz carrier range. If your drive uses a higher carrier (8–16 kHz), the core losses will increase and you may need to derate the current or switch to a reactor rated for that frequency band.","metaTitle":"SIDAC 4EU3652-0BF00-0AA0 Output Reactor, 120 A, 3.6 kHz","metaDescription":"SIDAC 4EU3652-0BF00-0AA0 output reactor, 3-phase AC, 120 A max, 3.6 kHz switching frequency, 0.3 mH, IP00, thermal class H.
