Ratings and what they mean for panel fit
The 3VA1025-4ED32-0JC0: The 25 A rated continuous current (Iu) holds flat from 40 °C up to 50 °C — no derating needed in a typical 40 °C panel ambient. Above that, it steps down: 24 A at 55 °C, 23.5 A at 60 °C, 23 A at 65 °C, and 22.5 A at 70 °C. If your enclosure runs hot from adjacent drives or transformers, that thermal curve is the one that governs real-world ampacity, not the nameplate 25 A. Breaking capacity at 415 V (75.6 kA) and 440 V (52.5 kA) covers most European and Asian industrial distribution networks where the available fault current at the panelboard can hit those levels. The 690 V rating (11.9 kA) is lower but still adequate for 690 V line-side applications with limited transformer kVA. These are the SCCR figures your coordination study needs — the breaker clears faults up to those levels without cascading upstream.
Configuration and integration
The breaker ships with a shunt trip (STL) auxiliary release and two auxiliary switches (HQ). The shunt trip order code is 3VA9688-0BL32 — that's the factory-matched accessory, not a generic substitute. No undervoltage release, no ground-fault monitoring, no communication module on this variant. The TM210 release is thermal-magnetic, so it's a standalone overcurrent protector with no electronic trip unit adjustments. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth. That 70 mm depth is the body only — allow clearance for the shunt trip wiring and the auxiliary switch terminals on top. The IP40 front protection means it's fine in a clean indoor panel; not rated for washdown or outdoor exposure.
