That thermal stability means you don't lose headroom in a warm panel unless ambient pushes past 50 °C. The TM240 thermal-magnetic release handles overloads and short-circuits without an electronic trip unit. Short-circuit breaking capacity varies with line voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. That's a healthy SCCR curve — at 480 V you're interpolating between the 440 V and 500 V figures, still well above typical available fault current for most industrial panels. Dimensions are 130 mm height, 101.6 mm width, 70 mm depth — a standard SENTRON 3VA footprint.","metaTitle":"Siemens 3VA1180-3GF42-0AA0 SENTRON MCCB, 80 A, 4-Pole, TM240","metaDescription":"Siemens SENTRON 3VA1180-3GF42-0AA0 molded case circuit breaker, 80 A continuous, 4-pole, TM240 thermal-magnetic release.
