The 101.6 mm width (4 in) and 70 mm depth (2.76 in) mean it occupies a standard MCCB footprint — no surprises when you slot it into an existing SENTRON or third-party distribution board. At 55 °C it steps to 39 A, at 65 °C to 38 A, and at 70 °C to 37 A. That's a gentle slope — you don't lose a full breaker size until you're well above typical panel ambient. Maximum power loss is 10.8 W, which matters for thermal coordination in a sealed enclosure.","metaTitle":"Siemens 3VA1140-4ED46-0AA0 SENTRON MCCB, 40 A, 4-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1140-4ED46-0AA0 molded case circuit breaker, 40 A, 4-pole, TM210 release.
