That thermal curve means it holds its rating across most standard panel ambient temperatures without forced cooling. The interrupting capacity is the headline number here: 220 kA at 240 V, dropping to 154 kA at 415 V and 121 kA at 440 V. That fixed thermal element and magnetic trip pair is the workhorse choice for feeder and distribution panels where you want simple, reliable coordination without electronic adjustment. At 76.2 mm wide (3 in), 130 mm tall (5.12 in), and 70 mm deep (2.76 in), this MCCB mounts on a standard DIN rail — the 3-pole width is a compact 3-module footprint, so it slots into a panel without eating up more rail than a 40 A breaker should. If you need remote tripping or status feedback, you're adding external accessories or stepping up to the electronic-trip version in the 3VA family.","metaTitle":"Siemens 3VA1140-6EF36-0AA0 SENTRON MCCB, 40 A, 220 kA","metaDescription":"Siemens 3VA1140-6EF36-0AA0 SENTRON molded case circuit breaker, 40 A rated at 40 °C, 220 kA interrupting at 240 V, 3-pole, TM240 release.
