It is a 4-pole unit with a TM220 thermal-magnetic release, rated 160 A continuous at 40 °C. The interrupting capacity is the headline spec here: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V — so the voltage class of your system determines whether this breaker has headroom for the available fault current.
Thermal derating — the number that matters when the cabinet runs hot
Above that, it derates: 156 A at 55 °C, 151 A at 60 °C, 147 A at 65 °C, and 142 A at 70 °C.
