It carries a TM240 thermal-magnetic release and is rated for 16 A continuous from 40 °C up to 55 °C — at 60 °C it derates to 15 A, so if you're packing this into a hot panel near a drive or transformer, that's the number to watch. The breaking capacity is where this breaker earns its keep: 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and still 17 kA up at 500 and 690 V. That kind of headroom means it handles high-fault utility feeds or large transformer secondaries without worrying about cascading upstream — a real advantage when you're coordinating a distribution board.
Power loss maxes at 10.6 W — not nothing, but manageable in a ventilated enclosure.
