Its interrupting capacity hits 187 kA at 240 V AC, dropping to 121 kA at 415 V and 75.6 kA at 440 V — numbers that matter when you need fault clearance without upstream fuse coordination.
Thermal derating is gradual: 160 A holds from 40 °C through 50 °C, then drops to 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. That means a panel ambient of 50 °C or below gets full ampacity; above that, the load schedule needs a small haircut.
Dimensions are 70 mm deep × 76.2 mm wide × 130 mm tall — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without re-drilling.
