It carries a continuous current rating of 50 A at 40 °C and holds that rating up through 50 °C, then derates to 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C — so in a warm enclosure you still get nearly full ampacity. Rated insulation voltage is 800 V, and the interrupting capacity varies by line voltage: 121 kA at 240 VAC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. That gives you solid SCCR headroom for most industrial service-entrance or feeder applications.
The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard SENTRON 3VA footprint. The 70 mm depth (2.76 in) leaves clearance behind a typical enclosure door.
