Integrator's note on the 3VA2163-7HL46-0AA0
The breaking capacity is 330 kA at 240 V AC, dropping to 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V — the 690 V figure is a steep derate, so confirm the fault level at your service voltage.
The ETU320 release is an electronic trip unit with adjustable overload and short-circuit settings — it gives you curve shaping that a thermal-magnetic can't. No undervoltage release, no voltage trigger, no communication function, and no ground-fault monitoring built in; if you need those, this isn't the variant.
Dimensions: 181 mm height, 140 mm width, 86 mm depth. No trip indicator on the front, so fault indication is via the ETU320's internal diagnostics or a separate auxiliary contact.
