The Siemens 4EM5316-6CB00 is a single-phase commutating choke (line reactor) designed for converter front-ends. It's rated for 45 A continuous (50 A max) at 400 V AC, 50 Hz, with an inductance of 0.97 mH and a relative inductive voltage drop of 4% at rated current. This is an IP00 component — no enclosure protection — so it's intended for installation inside a panel or cabinet where the environment is controlled. The 0.168 m height, 0.151 m width, and 0.139 m depth footprint needs to be accounted for in the panel layout. Power loss splits between the coil (28 W) and the iron core (52 W), totaling 80 W of heat to dissipate at full load. Thermal class B per IEC 60085 means the insulation system is rated for a 130 °C maximum hot-spot temperature, with a 40 °C ambient rating.
The 4EM5316-6CB00 carries a mature lifecycle status from Siemens — it's an established catalog item, not newly introduced and not flagged for phase-out. Availability is confirmed at time of quote through independent distribution channels. There is no official successor order code listed; the mature status suggests ongoing production support without an imminent last-time-buy window.
Integration Notes
The IP00 rating means no gasket or seal — mount it where the panel's own enclosure provides the environmental protection. Verify your converter's minimum bus voltage requirement against this drop. Single-phase design limits this choke to single-phase converter inputs. For three-phase applications, you'd need three units or a three-phase reactor.
