Breaking capacity runs from 440 kA at 240 V down to 53 kA at 690 V — that 440 kA figure at 240 V covers high-fault industrial services where the upstream transformer can deliver serious short-circuit current.
The ETU340 release is a solid-state trip unit with a fixed time delay tr of 1300 ms (both min and max settings), so it's set for selective coordination downstream: it lets a 25 A branch breaker clear a fault before this main trips.
Panel integration
An optional motor drive (product extension available per the spec) allows remote reset or switching. Communication function is not built in — this is a standalone breaker, no fieldbus module on board.
