The 3-pole frame carries a TM240 thermal-magnetic release — the thermal element handles overloads, the magnetic element clears short circuits — and the interrupting ratings climb to 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V.
At 55 °C it steps down to 76.8 A, then 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. If your panel ambient runs over 50 °C, the 80 A continuous current is still good for about 72 A at the top end of the operating range. The shunt trip coil part number is 3VA9688-0BL33. This is a straightforward line-protection breaker: thermal-magnetic, manually operated, with a voltage-trip option for emergency-off circuits.
