Above that it derates: 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. That 76.2 mm width is a standard 3-pole MCCB footprint — it fits the same panel cutout and bus-bar spacing as other SENTRON 3VA 3-pole frames. ## Auxiliary contacts and trip indication The trip alarm switch changes state only when the breaker trips on a fault — useful for remote fault annunciation or a shunt-trip circuit. A trip indicator is also built into the front, so a walk-by inspection shows a tripped breaker without opening the panel door. The mechanical endurance is rated at 15 000 operations.","metaTitle":"Siemens 3VA1150-5EF32-0AG0 MCCB, 50 A, 3-Pole, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA1150-5EF32-0AG0 molded case circuit breaker, 50 A rated continuous current, 3-pole, interrupting 187 kA at 240 V.
