It carries a 121 kA interrupting capacity at 240 V AC, dropping to 75.6 kA at 415 V and 52.5 kA at 440 V — the numbers you need for a fault-current study on a 480 V panel.
At 70 mm deep, 101.6 mm wide, and 130 mm tall, this MCCB occupies a standard 4-module-wide slot on a DIN rail. Maximum power dissipation is 12 W — account for that in your thermal budget if you're packing a row of these in a shallow enclosure.
Temperature derating and real-world current
At 60 °C and 65 °C it derates to 19 A, and at 70 °C it's still 19 A.
