It carries a rated current of 50 A at 40 °C ambient, with a 3-pole construction and an insulation voltage rated at 800 V. The 32 kA breaking capacity at 415 V is the figure that determines whether it clears a fault without upstream coordination issues in a 400 V panel. Breaking capacity drops as voltage rises: 52.5 kA at 240 V, 13.6 kA at 440 V, and 7.5 kA at 500 V and 690 V. For a 400 V distribution board, the 32 kA at 415 V is the relevant SCCR figure — verify it exceeds the available fault current at the point of installation.
The 50 A rating holds steady from 40 °C up to 50 °C, then begins to taper: 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. If the breaker sits in a crowded enclosure with poor airflow, use the 70 °C column for sizing — that 45 A figure is the real limit, not the catalog 50 A. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — standard 3-pole MCCB footprint for a DIN-rail or panel-mount installation.
