Breaking capacity across voltage — where this breaker fits
The 3VA2163-5MN32-0HA0: The interrupting ratings are voltage-dependent: 187 kA at 240 V, 121 kA at both 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. At 415 V — the common three-phase industrial voltage in much of the world — the 121 kA figure places this breaker in a high-interrupting-capacity class, suitable for installation close to a large transformer or in a main distribution panel. The sharp drop to 3.7 kA at 690 V means it should not be relied upon for high-fault clearing at that voltage; if your system runs 690 V, verify the available fault current stays below that threshold.
