Its breaking capacity reaches 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V — figures that tell you it can safely interrupt high fault currents without upstream cascading. The 160 A rating holds flat from 40 °C to 50 °C, then derates gradually to 150 A at 70 °C; that thermal curve matters if the breaker sits in a warm enclosure or next to other heat sources.
This MCCB occupies a 76.2 mm wide by 130 mm tall by 70 mm deep footprint — three standard 25 mm module widths on a DIN rail.
