63 A MCCB with thermal-magnetic trip and undervoltage release
Its breaking capacity reaches 187 kA at 240 VAC, 121 kA at 415 VAC, and 75.6 kA at 440 VAC — figures that govern fault-clearing capability at the point of installation.
Maximum power dissipation is 19.8 W — relevant for enclosure thermal calculations when grouping multiple breakers.
Mounting dimensions and panel fit
Width 76.2 mm (3 in), depth 70 mm (2.76 in), height 130 mm (5.12 in). Verify busbar spacing and enclosure depth against the 70 mm projection including the auxiliary switch stack.
