What it is and what it does
The Siemens SIDAC 4EM5308-3CB00 is a 1-phase smoothing choke rated for 690 V operating voltage and 10 A DC maximum current (9 A rated). Its 0.05 H inductance and 46.8 W coil power loss are sized for DC-link filtering in drives or power supplies — the 2.5 W energy content tells you it handles moderate ripple, not bulk storage.
Mounting and integration
Open-frame IP00 design — no enclosure, so it mounts inside a cabinet on a sub-panel or chassis. Dimensions are 0.151 m wide × 0.151 m high × 0.129 m deep. Screw-type or tab terminals for the main circuit; plan for 0.2–2.5 mm² copper wire with ferrules. Thermal class B (130 °C) per IEC 60085, ambient rated at 40 °C.
