At 240 V the interrupting rating reaches 242 kA, dropping to 187 kA at 415 V and 440 V, then 121 kA at 500 V, and 3.7 kA at 690 V.
Physical integration and panel fit
Dimensions are 181 mm height, 140 mm width, and 86 mm depth. The 140 mm width is standard for a 4-pole MCCB in the SENTRON 3VA frame — it fits the same cutout and bus-bar spacing as other 3VA2 breakers, so a panel designed for a 3VA2163-8JQ32-0AA0 will accept this unit without rewiring the main bus.
Trip unit and communication
The ETU850 electronic trip unit supports communication functions, enabling integration with energy management or remote monitoring systems. Power loss at maximum rated current is 25.5 W, which should be considered in enclosure thermal calculations.
