63 A MCCB for motor and starter protection
Rated 63 A continuously from 40 °C up to 70 °C, it holds its full ampacity across the typical panel ambient range without derating. Three poles, with a breaking capacity of 330 kA at 240 V and 242 kA at 415 V, so it safely interrupts high-fault currents in industrial low-voltage switchgear without cascading upstream. At 690 V the breaking capacity drops to 3.7 kA — still adequate for most 690 V motor circuits where the supply transformer limits fault current, but worth verifying against the site's available fault level if used on a 690 V bus.
Footprint: 105 mm wide × 181 mm tall × 86 mm deep. Fits standard 3-pole MCCB cutouts and busbar risers without adapter plates.
