It is configured as a line-protection device — meaning its trip curve is set for feeder and main-switch duty, not motor or generator protection. The 800 V rated insulation voltage (Ui) gives headroom for 690 VAC systems, and the interrupting ratings climb to 121 kA at 240 VAC, 75.6 kA at 415 VAC, 52.5 kA at 440 VAC, and 11.9 kA at 690 VAC — so it handles high-fault-current points of common coupling without cascading upstream.
Thermal derating and auxiliary contacts
Above that it derates: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C.
Panel fit and mechanical endurance
The 4-pole MCCB measures 101.6 mm wide, 130 mm tall, and 70 mm deep — a standard SENTRON 3VA footprint that drops into existing panel layouts without re-drilling. Front-face protection is IP40.
