What this output reactor does in the drive line
The Siemens SIDAC 4EU2532-0AC00-0AA0 is a 3-phase output reactor rated for a maximum continuous current of 150 A and a rated switching frequency of 10 000 Hz. It sits between the variable-frequency drive output and the motor cable, limiting the rate of voltage rise (dV/dt) and reducing capacitive charging currents that cause bearing fluting and motor insulation stress. The 0.000006 H inductance and 7.4 % impedance (at rated conditions) are sized for a 460 V AC line, with a thermal class H winding that holds up at 45 °C ambient.
Mounting and connection — IP00, flat terminals
The reactor measures 0.22 m wide by 0.21 m tall by 0.16 m deep and carries an IP00 protection class — no enclosure, so it must be mounted inside a panel or cabinet that provides the environmental seal. Main circuit connections are flat-type terminals (flat connector per the spec), which accept bus-bar or lug-style wiring common in drive output circuits. The open-frame construction means the installer needs to maintain clearance to grounded metalwork per the local code; the H-class insulation (180 °C rated) gives thermal headroom in a crowded cabinet.
