It carries 32 A continuously at 40 °C, and the rating holds flat through 50 °C before it starts to taper: 31 A at 55 °C, 30 A at 70 °C. That thermal curve means you don't have to oversize for a warm enclosure as long as ambient stays under 50 °C.
Breaking capacity — what the voltage columns tell you
This breaker's interrupting rating changes with system voltage, which is normal for an MCCB but worth checking against your available fault current. At 240 V it clears 52.5 kA; at 415 V that drops to 32 kA; at 440 V it's 13.6 kA; and at 500 V or 690 V it holds at 7.5 kA.
Envelope and panel fit
It's 70 mm deep, 76.2 mm wide, 130 mm tall — standard 3-pole MCCB footprint for a SENTRON 3VA frame. Depth of 70 mm leaves room for rear-connected busbars in a typical 200 mm deep enclosure.
No undervoltage release is fitted, so if your safety circuit requires a UVR on power loss you'd need a different variant or a field-installable accessory.
