What it is and what it does
The Siemens SIDAC 4EM5214-8CB00 is a 1-phase smoothing choke (Glaettungsdrossel) rated for 360V DC operating voltage, carrying a maximum continuous current of 98A with a rated value of 88.2A. Its 0.3mH inductance smooths the DC bus ripple on drives, inverters, or power supplies — the kind of job that keeps downstream capacitors and semiconductors from taking a beating. The 300Hz operating frequency tells you it's built for the switching side of a DC link, not line-frequency filtering. Total power loss runs 28.9W (28.1W in the coil plus 0.8W in the iron core), and it's wound to thermal class B per IEC 60085, meaning a 130°C hot-spot limit. That's standard for this size of DC choke — no derating surprises if the panel ambient stays under 55°C.
Mounting and connections
IP00 with free cable ends for the main circuit connection — so it's a panel-mount component, not something you bolt outside or near washdown. The footprint is 0.121m wide by 0.149m deep by 0.109m tall, which is compact for a 98A DC choke. Plan for the free conductor ends to land on a terminal block or busbar inside the enclosure; no plug-in convenience here.
Sourcing and lifecycle
Marked as mature lifecycle — meaning it's not in active promotion but still available through distribution channels. No official successor order code is listed. We source this against an RFQ; availability and current pricing get confirmed at quote time. If you're freezing a BOM or filling a repair, send the order code and we'll quote it.
