It carries a maximum breaking capacity of 187 kA at 240 V, tapering to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — the steep drop at the highest voltage tells you this breaker is optimized for 400 V class systems where the bulk of industrial fault duty lives.
The 690 V figure (3.7 kA) is a residual rating; this is not a 690 V primary breaker. The undervoltage release is absent, so if your safety circuit requires UVR, you need the variant that carries it.
Panel integration
The 3VA series uses the same mounting pattern as its predecessor, so a panel tooled for a 3VL or earlier SENTRON frame accepts this unit with no drilling changes.
