It carries an 80 A continuous current at 40 °C, with a thermal-magnetic TM210 overcurrent release providing LI (long-time and instantaneous) protection. The switching capacity class S rating means it delivers 121 kA at 240 V AC and 76 kA at 415 V AC — figures that govern its ability to safely interrupt fault currents without upstream cascading.
Rated current holds at 80 A from 40 °C through 50 °C, then derates to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. Operating ambient range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. Maximum power loss is 13 W.
Dimensions are 130 mm height, 50.8 mm width, 70 mm depth. The 2-pole width at 50.8 mm (2 inches) matches standard DIN-rail or panel-mount cutout spacing for SENTRON MCCBs. Front IP40 protection covers the operator interface; the breaker is not sealed for washdown environments.
