It carries a 242 kA breaking capacity at 240 V AC, dropping to 187 kA at 415 V and 440 V, 121 kA at 500 V, and 7.5 kA at 690 V — the voltage-dependent interruption performance tells you exactly where this breaker can clear a fault without upstream coordination issues. The 400 A rating holds flat from 40 °C through 50 °C ambient, then derates to 385 A at 55 °C, 370 A at 60 °C, 355 A at 65 °C, and 340 A at 70 °C.
Built-in auxiliary and release configuration
The base switch variant is 3VA2340-6HL32-0AA0, so the -0BL0 suffix adds the UVR and the HQ alarm package on top of that core breaker. A trip indicator is present, giving a local mechanical flag when the breaker has tripped on fault.
Dimensions are 248 mm high, 138 mm wide, and 110 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures designed for SENTRON 3VA2 breakers.
