Above that, the continuous current derates: 30.72 A at 55 °C, 30.08 A at 60 °C, 29.44 A at 65 °C, and 28.8 A at 70 °C.
Interrupting capacity across voltage levels
This MCCB delivers 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V. For most 400 V-class industrial panels, the 52.5 kA figure gives ample headroom against typical transformer-fed fault levels.
Auxiliary contacts and integrated shunt trip
The auxiliary release is a shunt trip (STL) — a voltage-triggered coil that lets a remote signal (E-stop, PLC output, pressure switch) open the breaker. If you need any of those, this is not the variant.
The 76.2 mm width is a standard 3-pole MCCB footprint — it occupies three 25.4 mm module spaces on a DIN rail or panel-mount base.
