It's a 3-pole unit rated 630 A continuous at 40 °C, with a maximum interrupting capacity of 242 kA at 240 V AC and 187 kA at 415 V AC — that's the short-circuit current it can safely clear without welding contacts or rupturing the case. Thermal derating is built into the spec: at 45 °C it's 612 A, at 50 °C it's 593 A, stepping down to 520 A at 70 °C. Maximum power loss is 162 W — that's heat that has to leave the enclosure, so factor it into your thermal budget.
Physical fit and integration
Dimensions are 110 mm deep, 138 mm wide, 248 mm tall. That's a standard MCCB footprint for this frame class — mounts in a distribution panel on a mounting plate or DIN rail adapter (not included). The trip indicator is present, so you get a visual flag after a fault event without needing to open the cover.
