Breaking capacity runs 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V, so it can interrupt high-fault currents on secondary-side transformers or bus risers without cascading upstream. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that fits SENTRON mounting plates and most DIN-rail adapter kits. Above that it derates gradually: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. Maximum power loss is 38 W at rated load. That's moderate for a 160 A frame; factor it into enclosure thermal calculations if you're stacking multiple breakers in a confined space.","metaTitle":"Siemens 3VA1116-3EF32-0AA0 SENTRON MCCB, 160 A, 3-Pole, TM24","metaDescription":"Siemens SENTRON 3VA1116-3EF32-0AA0 molded case circuit breaker, 160 A rated at 40 °C, 3-pole, TM240 thermal-magnetic release, 75.6 kA at 240 V.
