Its TM210 thermal-magnetic overcurrent release gives a fixed thermal pickup at 32 A (rated at 40 °C ambient, derating to 30 A at 70 °C) and a magnetic short-circuit trip calibrated to the line-protection curve. The 52.5 kA breaking capacity at 240 V AC is what you look at first for fault-clearing confidence in low-voltage switchgear; at 415 V it still interrupts 32 kA, which covers most industrial service-entrance and sub-distribution scenarios.
The 3VA1032-2ED32-0AF0 measures 130 mm high, 76.2 mm wide, and 70 mm deep — a compact 3-pole footprint that fits standard Siemens SENTRON mounting bases and busbar systems. The width (76.2 mm) is the critical dimension for multi-pole ganging in a row; it matches the 3VA family pitch, so you can line up adjacent breakers without odd gaps. Depth at 70 mm means it clears most standard enclosure back-panels with room for cable bending behind the terminals. The auxiliary switch configuration (1 auxiliary + 1 trip alarm switch HQ) is built into the supplied basic switch (3VA10322ED320AA0), so you get remote status and trip indication without an add-on module.
