The Siemens 3VA1032-2ED32-0AA0-ZD00 is a 3-pole IEC frame 100 molded case circuit breaker rated 32 A continuous current (In) with a fixed thermal-magnetic trip unit (TM210). The overload protection Ir is fixed at 32 A, and the short-circuit protection Ii is fixed at 10 x In — meaning it holds through 320 A peaks and trips magnetically above that. This breaker sits in a 3VA1 frame, which is the compact, panel-friendly chassis for 100 A frame ratings. The nut keeper kit and DC Power OEM designation in the description point to a variant kitted for a specific Chinese OEM DC power application — the keeper prevents the mounting nut from backing off under vibration in a power cabinet.
The fixed thermal-magnetic trip means no adjustment dials — set it and forget it, which suits a dedicated feeder or branch circuit where you don't want field tweaks. The nut keeper kit adds a locking feature for the mounting hardware, important if the panel sees transport vibration or is deployed in a mobile power system.
