It carries 80 A continuous current (Iu) through three poles, with a TM240 thermal-magnetic trip unit — meaning the thermal element handles overloads and the magnetic element handles short circuits, adjustable to a 1 s time delay at maximum (tr max). The interrupting capacity tells you where it fits: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V.
Thermal derating — the real-world current
Above that it starts to taper: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C.
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON distribution blocks and panelboards without re-drilling.
