63 A MCCB with ETU850 — 330 kA interrupting at 240 V
The interrupting ratings are the headline: 330 kA at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V. The trip range spans 95 A minimum to 756 A maximum, covering motor feeders, transformer primaries, and general distribution. Communication function is onboard, enabling integration with energy management or remote monitoring systems — useful for a plant engineer tracking load profiles without a panel walk.
The IP40 front protection suits indoor switchboard installation; the breaker mounts via the standard SENTRON 3VA2 baseplate or direct screw fixing. Power loss is 4 W maximum, low enough that ventilation spacing in a typical distribution panel is sufficient — no forced cooling required for this single unit.
