At 240 V the 3VA1025-3ED32-0CH0 interrupts 75.6 kA, at 415 V it clears 52.5 kA, at 440 V it handles 32 kA, and at 690 V it still breaks 7.5 kA. Those numbers span the common industrial voltage tiers — 240 V single-phase branch, 415 V three-phase distribution, and 690 V heavy plant — so the breaker gives selectivity headroom across a wide fault-current range without needing a larger frame.
Thermal derating and ambient tolerance
Rated continuous current holds at 25 A from 40 °C up to 50 °C, then derates to 24 A at 55 °C, 23.5 A at 60 °C, 23 A at 65 °C, and 22.5 A at 70 °C. That means in a warm panel — say 50 °C ambient — the breaker still delivers full 25 A without derating.
Undervoltage release and auxiliary contacts
The auxiliary trip module is order code 3VA9608-0BB24. That alarm contact is useful for remote fault indication on a PLC input or annunciator panel. The mechanical endurance is 15 000 operations.
Listed as current production. The 3VA1025-3ED32-0CH0 is in active manufacture and available through independent distribution.
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a compact 3-pole MCCB that mounts on a DIN rail or panel base. The auxiliary contact wiring is accessible without removing the breaker.
