It's a line-protection device, not a motor-protection or ground-fault variant. The 4-pole construction (100% N-conductor protection) makes it a fit for three-phase-plus-neutral distribution panels where you need to break all four poles. ## Breaking capacity — what the voltage tiers mean This breaker delivers 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. That's a steep drop above 440 V — at 690 V the interrupting rating is only 9% of the 240 V figure. The 415 V rating (121 kA) is the sweet spot for most European industrial distribution. At 55 °C it's 49 A; at 60 °C it's 48 A; at 65 °C it's 46 A; at 70 °C it's 45 A. That's a 10% drop from 50 °C to 70 °C. That's a 4-pole MCCB in a standard SENTRON 3VA frame — the width is the key dimension for DIN-rail or mounting-plate layout. Front IP40 protection; no communication module onboard. The design accepts an optional motor drive for remote tripping or re-closing.","metaTitle":"Siemens 3VA1150-5GE46-0AA0 SENTRON MCCB, 4P, 50 A, TM220, 18","metaDescription":"Siemens 3VA1150-5GE46-0AA0 SENTRON 4-pole molded case circuit breaker, 50 A rated, TM220 release, 187 kA breaking capacity at 240 V.
