Its 0.024 mH inductance limits the rate of current rise from the drive's PWM output, protecting motor windings from voltage spikes and reducing bearing currents on long cable runs. The 303 A maximum current (Ithmax) governs the reactor's thermal capacity under continuous load — size the upstream drive and motor so the full-load current stays at or below this figure. The 2000 Hz switching frequency matches modern IGBT drives; a reactor rated for 2 kHz will handle PWM carrier frequencies up to that point without saturating the core. Total power loss is 155 W (130 W coil + 25 W iron core) at rated conditions, which must be dissipated inside the enclosure — factor this into the panel's thermal budget. Thermal class H insulation (180 °C continuous) gives headroom for high-ambient or overload conditions. Mounting dimensions are 0.3 m wide by 0.26 m tall by 0.21 m deep — verify the enclosure backplate has clear space for these footprints plus the required air gap around the reactor for heat dissipation. Ambient temperature rating is 40 °C; derate the continuous current if the enclosure ambient exceeds that.","metaTitle":"SIDAC 4EU3052-0AR00-1BA0 Output Reactor, 303A, 2000 Hz","metaDescription":"SIDAC 4EU3052-0AR00-1BA0 output reactor, 3-phase AC, 303A max, 0.024 mH, 2000 Hz switching frequency, IP00, thermal class H.
