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.","metaTitle":"Siemens 3VA1116-3EF32-0AF0 SENTRON MCCB, 160 A, 3-Pole, TM24","metaDescription":"Siemens 3VA1116-3EF32-0AF0 SENTRON molded case circuit breaker, 160 A rated continuous current, 3-pole, TM240 thermal-magnetic release, 75.6 kA at 240 V.
