The 3VA1063-2ED42-0AA0: Breaking capacity is 52.5 kA at 240 V, 32 kA at 415 V, and 7.5 kA at 690 V — so it handles high fault currents on the low-voltage side and still clears on 690 V systems.
Dimensions are 130 mm tall, 101.6 mm wide, 70 mm deep — the 4-pole width is the key fit check for existing panel layouts. No undervoltage release, no shunt trip, no communication module — this is a basic thermal-magnetic breaker for straightforward line protection. Power loss is 17.3 W max at rated load, which matters for thermal calculations inside a sealed panel.
