Breaking capacity across voltage levels
The 3VA1116-5EF42-0AG0: This MCCB delivers 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. At 690 V the 17 kA rating still covers most industrial motor branch circuits.
Above that it derates: 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C. The breaker itself measures 70 mm deep by 101.6 mm wide by 130 mm tall, with IP40 protection on the front face. That width is a standard 4-pole MCCB footprint; it drops into a SENTRON 3VA mounting base without panel modification.
