Line protection version means it's configured for feeder or main breaker duty, not motor circuit protection — no adjustable long-time or instantaneous bands beyond the TM210's fixed thermal/magnetic curve. Width is 3 in, which matches the standard SENTRON 3VA frame footprint for panel cutouts and busbar risers. The shunt trip (STL) release allows remote tripping via a control voltage — useful for emergency-stop chains or PLC-driven load shedding. No undervoltage release is fitted, and no communication module is onboard; this is a straightforward power breaker, not a smart metering device. At 55 °C it derates to 78 A, at 60 °C to 77 A, at 65 °C to 75 A, and at 70 °C to 74 A. That's a shallow curve — you lose only 6 A over a 30 °C rise — which means this breaker can live in a warm panel without a big oversize step. If your enclosure ambient runs 65 °C, plan for 75 A continuous load max.","metaTitle":"Siemens 3VA1140-6GF46-0KF0 SENTRON MCCB, 80 A, 76 kA at 240","metaDescription":"Siemens SENTRON 3VA1140-6GF46-0KF0 molded case circuit breaker, 80 A rated, 76 kA at 240 V.
