What the 25 kA breaking capacity means for your panel
The 3VA1132-3ED32-0AA0-ZD00 is a 3-pole IEC frame 160 molded-case circuit breaker from the Siemens 3VA1 series, rated for breaking capacity class N with Icu = 25 kA at 415 V AC. The fixed thermal-magnetic trip (TM210) gives you Ir = 32 A overload protection and Ii = 10 × In (320 A) short-circuit instantaneous pickup. No adjustable thermal dial here; the Ir is locked at 32 A, so the BOM line is fixed once specified.
