Interrupting capacity — what it clears and where
This MCCB's interrupting capacity varies with system voltage, and that's the number you need for your fault study. At 240 V it clears 75.6 kA; at 415 V it's rated 52.5 kA; at 440 V it drops to 32 kA; and at 500 V or 690 V it holds at 11.9 kA.
Thermal performance and panel fit
At 55 °C it's 62 A, at 60 °C it's 61 A, and at 65 °C it's 60 A, with the floor at 58 A at 70 °C. Physical footprint: 130 mm tall, 76.2 mm wide, 70 mm deep — that's a standard MCCB form factor for a 3-pole 63 A frame.
