That's a solid thermal curve for a panel that runs warm. Breaking capacity is 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. It's a 3-pole unit, line-protection design, with a communication function onboard and a trip indicator.
That's a standard 3-pole MCCB envelope for this class — it'll drop into a SENTRON 3VA2 mounting base or a panel that's already cut for a 105 mm wide breaker. No surprises on the gland plate.
