The breaking capacity climbs to 187 kA at 240 V AC and stays at 121 kA through 440 V AC — at 690 V it drops to 4.25 kA, so this is a high-interrupting-capacity frame sized for low-voltage main feeders or large subfeeds where fault current is high. Temperature derating is already baked in: at 40 °C through 50 °C it holds the full 160 A; at 55 °C it drops to 154 A, and at 70 °C it's 136 A. The ETU560 is a microprocessor-based release with LSI (long-time, short-time, instantaneous) protection curves, plus ground-fault monitoring via summation current on the L-conductor. Communication function is built in, so the breaker can report status and trip events to a higher-level system. That's enough to signal remote status without adding an external contact block.
Dimensions are 105 mm wide, 181 mm high, 86 mm deep — a standard 3-pole MCCB footprint for a 160 A frame. Power loss is 28 W maximum at rated current; factor that into the enclosure thermal budget if the panel is sealed. The basic switch is order code 3VA2116-5JQ32-0AA0, and the integrated auxiliary trip is 3VA9608-0BB25 — these are the internal sub-assemblies if you ever need a replacement release or contact module.
