It carries a 242 kA interrupting capacity at 240 V, dropping to 187 kA at 415 V and 440 V, then 121 kA at 500 V, and 7.5 kA at 690 V — the steep fall at 690 V tells you this breaker is optimized for 240–500 V distribution, not 690 V motor circuits.
Standard DIN-rail or screw-mount pattern matches the 3VA2 family, so a swap from a 3VA2 of the same frame size is direct.
