What it is and what the ratings mean for fit
The Siemens 3VA1032-3ED36-0JA0 is a 3VA1 IEC frame 100 circuit breaker with a 32 A fixed thermal-magnetic trip unit (TM210) and a 25 kA breaking capacity at 415 V (class N). The fixed Ir=32 A means no dial adjustment — what you order is what protects the branch — and the fixed Ii=10 x In (320 A) short-circuit pickup gives a predictable magnetic trip point for coordinating downstream. The shunt trip (STL) operates on 110-127 V DC or AC 50/60 Hz, letting a remote E-stop or safety relay drop the breaker without pulling the handle.
Where it goes in the panel
This breaker lands on a DIN rail inside an IEC distribution or motor-control center. The clamp connection speeds wiring — no lug torquing for the line and load sides. The 3-pole form covers three-phase loads; the shunt trip adds a control-wire pair for remote tripping. Panel space is the same as any 3VA1 frame 100 unit, so if you're swapping an older 3VA or 3VL breaker, check the mounting footprint first.
