Its breaking capacity reaches 121 kA at 240 VAC, 75.6 kA at 415 VAC, and 52.5 kA at 440 VAC — figures that cover most low-voltage fault scenarios in commercial and light industrial installations.
Thermal derating and continuous current
Above that it derates: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C.
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint that fits existing SENTRON mounting plates and DIN-rail adapters without re-drilling.
