At 55 °C it carries 495 A, and at 70 °C still holds 480 A, so it handles warm enclosures without a frame size jump. Breaking capacity is the headline: 330 kA at 240 V, 242 kA at 415 V and 440 V, and 52.5 kA at 690 V.
Front IP40 protection keeps out tools and fingers; the back and sides rely on the enclosure. The basic switch core is order code 3VA2450-7MN32-0AA0, and the integrated shunt trip is 3VA9688-0BL32, so replacement or spare-part ordering is direct.
330 kA at 240 V, 242 kA at 415 V and 440 V, and 52.5 kA at 690 V. That covers high-fault industrial feeds.
