Breaking capacity is specified at four voltage points: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. The overcurrent release is a TM210 thermal-magnetic type — fixed thermal and magnetic settings, no electronic adjustment. That keeps the part simple for standard feeder protection but means you cannot dial in a lower magnetic pickup for a long motor start.
Above that it steps down: 24 A at 55 °C, 23.5 A at 60 °C, 23 A at 65 °C, and 22.5 A at 70 °C. If the panel ambient runs near 60 °C, the breaker is effectively a 23.5 A device — factor that into the load schedule. Front-face protection is IP40, so it keeps out tools and fingers but is not sealed against hose-down. Mount it inside a panel rated for the environment.
Not a switching duty device for frequent motor starts.
