Three poles, 160 A continuous current, and an ETU350 electronic trip unit that gives you adjustable long-time (tr 0.5–17 s) and short-time delay (tsd up to 0.4 s) for selectivity coordination downstream. At 240 V it clears 242 kA — that is utility-grade fault current, typical for a main breaker on a large transformer secondary. At 415 V and 440 V it still holds 187 kA, and at 500 V it manages 121 kA. Only at 690 V does it drop to 4.5 kA, which still covers most industrial motor-circuit faults at that voltage. That is unusual; most MCCBs start derating above 40 °C. The ETU350 release lets you dial in the protection curve to match your load, which is what makes this breaker suitable for both feeder and downstream distribution without swapping trip units.
That is standard for panel-mounted breakers; keep it behind a locked door or a gland plate if the environment is wet. The ETU350 is a solid-state trip unit with no communication function — no Modbus or PROFIBUS onboard, so fault reporting is local via the LED indicator and mechanical flag. Latching endurance of 20 000 operations.
