Per the datasheet, it carries a breaking capacity of 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V — so the SCCR headroom is substantial for most industrial distribution panels. The motor protection designation means it includes phase failure detection and a voltage trigger, making it suited for motor branch circuits where loss-of-phase protection is required.
Derating begins at 55 °C (495 A), dropping to 480 A at 70 °C. Dimensions are 248 mm height, 138 mm width, and 110 mm depth, so it fits standard MCCB mounting footprints.
The ETU350M release is the overcurrent protection brain — it's an electronic trip unit with adjustable settings (the specific curve parameters are in the full datasheet).
