Four poles give you the ability to switch all three phases plus neutral in a single enclosure, which simplifies wiring in 3-phase+neutral distribution and avoids a separate neutral disconnect. ## Breaking capacity — where it clears faults The interrupting ratings span the voltage range you'd expect in industrial distribution: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. That 52.5 kA at 415 V is the figure most panel builders will check first for European 400 V-class systems — it gives headroom above the typical 25–36 kA prospective fault current in most commercial switchboards. Dimensions are 70 mm deep, 101.6 mm wide, 130 mm tall — a 4-pole MCCB that fits standard SENTRON mounting feet on a DIN rail or panel-mount backplate.","metaTitle":"Siemens 3VA1150-3GF46-0AA0 SENTRON MCCB, 50 A, 4-Pole, TM240","metaDescription":"Siemens SENTRON 3VA1150-3GF46-0AA0 molded case circuit breaker, 50 A rated, 4-pole, TM240 release.
