Its interrupting capacity hits 220 kA at 240 VAC, 154 kA at 415 VAC, and 121 kA at 440 VAC — numbers that put it in the high-fault tier for industrial distribution panels where upstream transformer capacity is substantial. The TM240 release provides thermal overload and magnetic short-circuit protection for line protection.
Built-in undervoltage release and auxiliary switches
The UVR drops the breaker on loss of control voltage, which is standard for safety disconnects and emergency-off circuits where you want the breaker to latch out after a voltage dip. Trip indicator is not fitted; status comes from the aux switches.
Rated 63 A from 40 °C through 50 °C ambient; derating begins at 55 °C (60.48 A) and drops to 56.7 A at 70 °C. That's a clean thermal curve — no surprise drop at 45 °C. Front protection is IP40, so it's fine for enclosed switchboards but not washdown areas.
