Its breaking capacity reaches 75.6 kA at 240 V AC, 52.5 kA at 415 V, and 32 kA at 440 V, with a floor of 7.5 kA at 500 V and 690 V. It is designed without ground-fault monitoring or communication functions, and no trip indicator or voltage trigger is present.
The 63 A rating holds flat from 40 °C through 50 °C, then derates gradually: 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C. Maximum power loss is 19.8 W.
The 3-pole footprint fits standard SENTRON panel cutouts and busbar systems. The 70 mm depth leaves clearance for rear-connected cable lugs or busbar adapters in a typical 200 mm deep enclosure.
