Its interrupting capacity hits 187 kA at 240 V, dropping to 121 kA at 415 V and 440 V, 79 kA at 500 V, and 4.25 kA at 690 V — so the 240 V figure is the headline, but the 415 V and 440 V numbers are what matter for most industrial 400 V-class distribution panels.
Thermal derating — the real continuous current
At 55 °C it derates to 96.25 A, at 60 °C to 92.5 A, at 65 °C to 88.75 A, and at 70 °C to 85 A.
Footprint and panel fit
Dimensions are 105 mm wide, 181 mm high, 86 mm deep — a standard SENTRON 3VA frame size for a 100 A, 3-pole MCCB.
