The 3VA1140-6EF36-0BH0: The headline breaking capacities tell you where this breaker can safely interrupt a fault: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 690 V. The 40 A rating holds across 40 °C to 50 °C ambient, then derates to 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, and 36 A at 70 °C. Suitable for dry indoor panel mounting where splash is not expected.
Auxiliary contacts and undervoltage release — what's on board
The auxiliary contacts follow the main contact position; the alarm switch changes state only on a trip event (overload, short circuit, or undervoltage). That alarm contact is useful for remote fault annunciation without adding a separate monitoring relay. An undervoltage release (UVR) is fitted as standard. The integrated auxiliary trip order code 3VA9608-0BB11 is the factory-matched accessory for this breaker — if you need a spare or replacement UVR module, that's the number to order.
No official successor has been published because none is needed — this is the current-generation SENTRON 3VA platform.
Panel fit — dimensions and mounting
The breaker measures 130 mm high, 76.2 mm wide (3 inches — standard MCCB pole spacing), and 70 mm deep. Fits a standard DIN-rail or screw-mount panel footprint; the 76.2 mm width means three poles occupy roughly the same space as three single-pole units ganged.
