It's a 3-pole unit rated 160 A continuous current, with a breaking capacity that starts at 242 kA at 240 VAC and holds 187 kA at 415 V and 440 V, then drops to 121 kA at 500 V and 3.7 kA at 690 V.
The shunt trip (STL) release is built in, so you can remotely trip the breaker from a safety circuit or emergency-stop chain. Two auxiliary switches HQ are also fitted, giving you status feedback (open/closed) for a PLC or annunciator without adding external blocks. Power loss is listed at 25.5 W maximum — that's the heat this breaker dumps into the enclosure at full rated current. For a panel designer, that number drives ventilation or derating of adjacent devices.
No communication function on this variant, so it's a standalone thermal-magnetic or electronic-trip breaker (the evidence doesn't specify trip type, but the line-protection designation and shunt trip point to a standard industrial MCCB).
