Breaking capacity hits 75.6 kA at 240 V and still clears 52.5 kA at 415 V, so it handles high-fault utility feeds common in industrial switchgear.
At 240 V the breaker clears 75.6 kA; at 415 V that drops to 52.5 kA, then 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. That curve tells you the 3VA1132-3ED46-0AA0 is sized for 480 V or 600 V class panels where the available fault current stays under 12 kA — common in North American 480Y/277 V distribution. The thermal derating is flat from 40 °C through 50 °C at 32 A, then steps down to 31 A at 55–60 °C and 30 A at 65–70 °C.
Panel fit and physical integration
The 3VA1132-3ED46-0AA0 measures 101.6 mm wide, 130 mm tall, and 70 mm deep — a 4-pole MCCB that fits standard Siemens SENTRON mounting feet and busbar connections.
