The 3VA1112-3EF32-0BC0: The TM240 release is a fixed thermal-magnetic design — no interchangeable trip units, so what you see on the nameplate is what you get. Breaking capacity runs 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V. That covers most industrial service-entrance and panelboard applications; the 415 V figure is the one to check against your transformer secondary fault current.
This breaker carries an undervoltage release (UVR) as the auxiliary release — part number 3VA9608-0BB11 integrated at the factory. The auxiliary contact version is 2 HQ switches. Panel builders: the UVR coil needs its own control power; verify polarity on the free-wheel diode if you're wiring it into a safety circuit.
Footprint: 130 mm high, 76.2 mm wide, 70 mm deep. That 76.2 mm width is three 25.4 mm pole spaces — standard for a 3-pole MCCB in a Siemens panelboard or any DIN-rail adapter kit. IP40 on the front means it's fine in a clean indoor enclosure; keep it out of washdown zones.
Rated insulation voltage is 800 V, so it's comfortable on 480/277 V or 600 V systems with headroom. Storage range -40 °C to 80 °C; operating -25 °C to 70 °C. The thermal derating curve is flat from 40 °C to 50 °C at 125 A, then drops to 120 A at 55 °C, 117.5 A at 60 °C, 115 A at 65 °C, and 112.5 A at 70 °C — useful if the breaker lives near a hot transformer or in a non-conditioned space.
