What this 630 A MCCB covers
The 630 A is the minimum and maximum current rating — it is not adjustable, so the load must match that value exactly. Breaking capacity runs from 187 kA at 240 V down to 11.9 kA at 690 V, so the available fault current at the installation point determines whether this frame is adequate.
Above that it derates: 618 A at 55 °C, 607 A at 60 °C, 595 A at 65 °C, and 583 A at 70 °C.
Accessories and auxiliary configuration
The basic switch is order code 3VA14635GF420AA0. If you need communication or ground-fault, this is not the variant — you would step to a different suffix in the 3VA1 family.
Physical fit
Dimensions are 248 mm high, 184 mm wide, and 110 mm deep. The 4-pole frame mounts in a standard distribution panel footprint.
