Breaking capacity is 440 kA at 415 V and 187 kA at 690 V — that's high-end for a 63 A frame, giving you headroom for fault currents in large distribution panels or transformer secondaries. The 3-pole construction with an ETU350M electronic release means you get adjustable trip class (10A, 10E, 20E) and phase failure detection built in, which is what you want for protecting a motor branch circuit where single-phasing is the common failure mode.
Footprint is 105 mm wide by 181 mm tall by 86 mm deep — standard 3-pole MCCB envelope for a 63 A frame, so it drops into existing SENTRON 3VA panel layouts without re-drilling. IP40 on the front is typical for switchboard mounting; no gasketing for washdown, so keep it inside a dry enclosure.
