In a mining or mill environment where crusher drives and conveyor feeders pile up fault current, this breaker shrugs off the vibration and the fault energy, rated for combustible dust and abrasive slurry. At 55 °C it drops to 48 A, at 60 °C to 47 A, and at 70 °C to 45 A. If your panel ambient sits at 55 °C and the load is 49 A, this breaker is undersized; step up to the next frame. The interrupting curve tells you where this breaker lives: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. At 690 V the available fault current must be under 17 kA — typical for a 690 V mining shovel or conveyor drive, but verify the transformer impedance. That gives you one NO/NC for status feedback and one dedicated alarm contact that closes only on a trip — essential for a remote SCADA alarm in a mill or pit. The 3VA1150-5EF36-0AF0 measures 76.2 mm wide, 130 mm tall, and 70 mm deep. In a mill MCC room with airborne ore dust, IP40 on the front is fine as long as the enclosure itself is sealed.","metaTitle":"Siemens 3VA1150-5EF36-0AF0 SENTRON MCCB, 50 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1150-5EF36-0AF0 molded case circuit breaker, 50 A rated, 3-pole, line protection, 187 kA at 240 V.
