Its 100 A rated continuous current (Iu) holds at ambient temperatures up to 50 °C before derating begins — at 55 °C it carries 96 A, at 60 °C it carries 94 A, and at 70 °C it still delivers 90 A, so the thermal curve is mild enough that a 100 A feeder in a warm panel stays within rating without oversizing. Interrupting capacity is 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V — these are the fault currents the breaker can safely clear without welding or rupturing, which means the 3VA1010-2ED32-0CA0 is sized for high-fault industrial distribution panels, not just light commercial service.
Fit and panel integration
The 3VA1010-2ED32-0CA0 measures 130 mm high, 76.2 mm wide, and 70 mm deep — a three-pole MCCB in a standard SENTRON 3VA footprint that drops onto a DIN rail or mounts directly to a backplate.
