The 80 A rating holds flat from 40 °C through 50 °C, then begins a gentle roll-off: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C.
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount bases in the SENTRON 3VA family.
The interrupting capacity is 121 kA at 240 V AC, with 75.6 kA at 415 V and 52.5 kA at 440 V.
TM240 means the thermal element is rated 80 A and the magnetic pickup is set at 240 A — a 3x multiple suitable for line protection against moderate inrush.
