It carries a rated continuous current Iu of 160 A across three poles, with a TM240 thermal-magnetic release — meaning the thermal pickup is fixed at 160 A and the magnetic short-circuit trip is set at 240 A (the TM240 designation). The interrupting ratings climb to 75.6 kA at 240 V and 52.5 kA at 415 V, so it handles substantial fault currents without cascading upstream. It's a straightforward thermal-magnetic MCCB for feeder or main breaker duty where you don't need add-on electronics.
Above that it begins to taper: 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C.
The 3VA1116-3EF32-0AF0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. The 76.2 mm width (three-pole) is the standard 3-module MCCB footprint for this frame size — it occupies three 25.4 mm pole centers. The trip indicator is visible through the front cover, so a quick glance tells you whether the breaker tripped on overload or short circuit.
