Breaking capacity is 52.5 kA at 240 V AC, dropping to 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 500/690 V. That 52.5 kA at 240 V covers high-fault service-entrance applications; the 7.5 kA at 690 V still handles most motor-circuit fault levels on 690 V industrial networks. Maximum power loss is 25 W — a figure to factor into enclosure thermal calculations when grouping multiple breakers.
Built-in accessories and integration
Dimensions are 130 mm height, 76.2 mm width (3 in), 70 mm depth — a standard SENTRON 3VA1 footprint that drops into existing panel cutouts and busbar systems without re-drilling. The basic switch core is order code 3VA10102ED320AA0, so replacement of the switching mechanism alone is possible if the accessory tray is reused. The breaker has no communication function or trip indicator — it is a straightforward thermal-magnetic line-protection device, not a metering or smart breaker.
