It's a 3-pole unit rated 160 A continuous at 40 °C with a TM240 thermal-magnetic overcurrent release — meaning the thermal pickup is fixed at 160 A, and the magnetic instantaneous trip is adjustable around 240 A. The interrupting capacity hits 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V, dropping to 11.9 kA at 500 V and 690 V.
At 55 °C it's 158 A, at 60 °C it's 155 A, at 65 °C it's 153 A, and at 70 °C it's 150 A. Maximum power loss is 38 W — that's the heat this breaker dumps into the enclosure, so factor it into the thermal budget if you're stacking several in a tight cabinet. The trip indicator gives a visual flag when the breaker has tripped on overcurrent — useful for a quick panel walk-down without opening doors. The auxiliary switch configuration is 1 auxiliary switch + 1 trip alarm switch HP, so you get both a status signal and a separate alarm on trip.
Designed for line protection, so it's the main or feeder breaker, not a motor-protective device.
