It's a 3-pole unit rated at 160 A continuous, with a breaking capacity that scales with system voltage — 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, 17 kA at 500 V, and 11.9 kA at 690 V.
At 55 °C it drops to 156 A, at 60 °C to 151 A, at 65 °C to 147 A, and at 70 °C to 142 A. The rated insulation voltage is 800 V, so it's comfortable on 480/277 V and 600/347 V systems with headroom. That's the coil that drops the breaker on loss of control voltage, common in safety circuits and emergency-stop chains. Power loss is 35.5 W maximum at rated load. That's modest for a 160 A frame, but if you're packing multiple breakers in a small enclosure, the cumulative heat matters for the thermal derating curve above.
Dimensions: 105 mm wide, 158 mm tall, 70 mm deep.
