The front-face protection class is IP40, so it's suited for installation inside a dry enclosure where tools or fingers won't contact live parts.
Breaking capacity — what the voltages tell you
Breaking capacity varies sharply with system voltage: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V.
Built-in undervoltage release and auxiliary contacts
That's a standard requirement for safety circuits and machinery directives.
The 76.2 mm width (3 inches) is the standard 3-pole MCCB footprint for this current range — it fits the same panel cutout and busbar spacing as other SENTRON 3VA frames. Depth of 70 mm means it clears most standard enclosure depths without interference, but verify clearance for the undervoltage release wiring and auxiliary cable exit.
