Breaking capacity hits 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. The adjustable thermal-magnetic trip is set between 95 A minimum and 756 A maximum (the latter is the short-circuit release; the 63 A frame governs continuous load).
The 187 kA at 240 V is the interrupting rating you need for a high-fault service entrance; at 415/440 V the 121 kA still covers most industrial distribution. The adjustable trip range (95 A to 756 A) lets you coordinate with downstream devices without swapping the breaker body. This is a standard-size SENTRON 3VA2 frame — it fits existing 3VA panel cutouts and busbar arrangements without modification.
