What it is and where it lands
The Siemens 4EM5215-1CB00 is a commutating choke (line reactor) for converter applications, single-phase, rated 30 A continuous with a 32 A maximum thermal current. It's built for 500 V AC systems, 0 to 60 Hz, with an inductance of 0.0014 H. The IP00 open-frame construction means it mounts inside a cabinet — no touch protection on the core itself, so it goes in a panel with a locked door or a separate enclosure. Terminal connections are screw-type, sized for the rated current.
What the ratings mean for fit
The 30 A rated current (32 A max) is the continuous thermal limit at 40 °C ambient, thermal class B per IEC 60085. That 30 A is the figure to size against your converter's input current — not the peak or surge. The 0.0014 H inductance provides the commutation notching and dV/dt smoothing a converter's input bridge needs; the 3.3 % relative inductive voltage drop (UK) at rated current tells you the choke will drop about 3.3 % of line voltage under load, which matters for voltage-budget calculations on the DC bus. The 0 to 60 Hz operating frequency range covers both 50 Hz and 60 Hz line supplies. At DC, the same choke carries 39.2 A — useful if you're using it on the DC side of a single-phase rectifier.
Panel integration note
At 0.128 m deep, 0.121 m wide, and 0.131 m tall, the 4EM5215-1CB00 is a compact block for a 30 A choke. No DIN-rail clip — it's a foot-mount or through-bolt chassis mount inside the panel. The IP00 rating means no enclosure on the choke itself; plan for at least 10 mm air gap to adjacent live parts for creepage at 500 V. Screw terminals accept the cable lug size appropriate for 30 A; torque to the value on the nameplate.
