What this MCCB delivers in a panel
It is a current-production part (lifecycle stage: current), so you are specifying a breaker Siemens plans to support. The 3-pole design handles three-phase loads, and the ETU560 electronic trip unit gives you adjustable time-current curves (tr from 0.5 to 25, tsd up to 0.5 s) for selectivity downstream.
This MCCB's interrupting rating is specified at multiple system voltages: 440 kA at 240 V, 330 kA at both 415 V and 440 V, 220 kA at 500 V, and 53 kA at 690 V. The 53 kA at 690 V is still well above typical industrial SCCR requirements; you are not bumping into limits even on 690 V mining or marine supplies.
Thermal performance and enclosure planning
Power loss is only 1.2 W maximum, so heat buildup inside the enclosure is minimal.
Communication and monitoring capability
That means you can integrate it into a higher-level monitoring system — useful for predictive maintenance or remote trip indication. The ETU560 release allows adjustable response times for both long-time (tr) and short-time (tsd) protection, giving you selectivity coordination with downstream breakers.
