That thermal curve matters if this breaker sits near other heat sources on the DIN rail; a panel builder should check the ambient at the breaker's location, not just the room ambient. You spec the breaker for the load, not the other way around. No trip indicator means you won't get a visual flag when it opens — the handle position is your cue. The 3VA1140-3GD46-0AA0 measures 70 mm deep, 101.6 mm wide, and 130 mm tall — a four-pole MCCB that fits a standard distribution panel footprint.","metaTitle":"Siemens 3VA1140-3GD46-0AA0 SENTRON MCCB, 40 A, 4-Pole, 75.6","metaDescription":"Siemens 3VA1140-3GD46-0AA0 SENTRON molded case circuit breaker, 40 A, 4-pole, interrupting 75.6 kA at 240 V.
