At 415 V the breaking capacity drops to 76 kA, at 440 V to 53 kA, and above 500 V it settles at 11.9 kA through 690 V. That steep curve means you need to check the actual line-to-line voltage at the fault point — specifying this breaker on a 690 V feeder without confirming the 11.9 kA headroom will leave you with a coordination gap. Above that it starts to taper: 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C.","metaTitle":"Siemens 3VA1150-4EE46-0AA0 SENTRON MCCB, 4-pole, 50 A, 121 k","metaDescription":"Siemens SENTRON 3VA1150-4EE46-0AA0 molded case circuit breaker, 4-pole, 50 A rated, 121 kA breaking at 240 V.
