Its 63 A rated continuous current holds at ambient temperatures up to 50 °C without derating; above that the curve steps down to 60.48 A at 55 °C and 56.7 A at 70 °C, per the datasheet. The 3-pole design fits standard MCCB mounting footprints in distribution panels.
It mounts into the standard MCCB cutout or on a mounting plate within an enclosure. The 105 mm width occupies one standard MCCB pole space per pole. Maximum power loss is 75 W, so ventilation or derating within sealed enclosures should be checked against the thermal curve above 50 °C.
