Its 100 A rated continuous current (Iu) holds at ambient temperatures up to 50 °C before any derating kicks in — at 55 °C it still carries 96 A, and at 70 °C it's good for 90 A, so you don't lose headroom in a warm enclosure. Breaking capacity is the number that decides whether this breaker clears a fault without upstream damage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V.
The 3VA1010-3ED36-0HH0 measures 70 mm deep, 76.2 mm wide, and 130 mm high — a standard MCCB footprint that fits most DIN-rail or panel-mount enclosures without surprises. The integrated auxiliary trip order code is 3VA9688-0BL30 if you need a replacement.
