The interrupting capacity reaches 440 kA at 240 V, 330 kA at 415 V, and still 52.5 kA at 690 V — so it clears high-fault scenarios without cascading upstream.
The undervoltage release is absent on this variant (no voltage-trip coil), and there's no ground-fault monitoring module — those are add-on options if your application needs them.
What the ETU850 trip unit gives you
The ETU850 is an electronic trip unit with adjustable overload (Ir) and short-circuit (Isd, Ii) settings, plus ground-fault alarm capability (though this breaker ships without the ground-fault monitoring module). It also supports communication — the 'Communication Function: Yes' flag means it's ready for a plug-in module or direct bus connection for remote monitoring.
