It's a line-protection device — meaning it's tuned for feeder and main distribution, not motor-starting duty where you'd want a different trip curve. At 415 V and 440 V it still holds 121 kA, and it's still good for 79 kA at 500 V. No ground-fault monitoring, no voltage trigger, no communication module — it's a straight-ahead thermal-magnetic replacement with electronic precision. That means you get better temperature stability and tighter band tolerances than a thermal bimetal, but you don't get the bells and whistles of a communicating breaker. For a standard distribution board or a main feeder in an industrial panel, that's exactly what you want.
Temperature derating — don't get caught out
At 55 °C it derates to 154 A, at 60 °C to 148 A, and at 70 °C to 136 A.
Physical fit and auxiliary contacts
It ships with two auxiliary switches (HP type) built in, so you've got status feedback for your PLC or indication lights without buying a separate accessory.
