Breaking capacity hits 187 kA at 240 V and 121 kA at 415/440 V, then drops to 79 kA at 500 V and 3.4 kA at 690 V. That 187 kA figure covers high-fault utility feeds; the 3.4 kA at 690 V is still adequate for most 690 V distribution, but verify your available fault current at that voltage before committing the BOM line.
The 105 mm width occupies three pole spaces on a DIN rail — plan for adjacent breaker spacing and busbar takeoff.
The ETU350 is an electronic trip unit that provides adjustable overload and short-circuit protection curves, so you can match the trip characteristic to motor or feeder loads without swapping the breaker.
