The breaker sits in a standard panel or enclosure footprint: 101.6 mm wide, 130 mm tall, 70 mm deep, with IP40 protection on the front face.
This MCCB carries a 220 kA interrupting rating at 240 V, dropping to 154 kA at 415 V, 121 kA at 440 V, and 17 kA at both 500 V and 690 V. At 690 V the 17 kA rating is still substantial for a 63 A frame; you can coordinate this breaker downstream of a larger feeder without worrying about cascading failure.
Thermal derating — real-world current handling
At 55 °C it derates to 62 A, at 60 °C to 61 A, at 65 °C to 60 A, and at 70 °C to 58 A. Power dissipation tops out at 17.3 W, which is manageable for thermal budgeting in a multi-breaker panel.
