Line-up and breaking capacity
Its TM240 thermal-magnetic overcurrent release provides fixed overload and short-circuit protection for feeder circuits in distribution panels. Breaking capacity is the standout spec here: 220 kA at 240 V, tapering to 154 kA at 415 V, 121 kA at 440 V, and still 17 kA at 690 V.
Above that it derates: 15.36 A at 55 °C, stepping down to 14.4 A at 70 °C. For a panel OEM wireman, that means if the enclosure ambient runs at 55 °C, the breaker can only carry 15.36 A continuously — factor that into your branch circuit sizing. Front protection is IP40. If you need shunt trip or remote signaling beyond the aux contacts, you'll add those externally.
