Its interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — figures that govern selectivity coordination in high-fault-current panels, not just the breaker's own withstand. The front face carries IP40 protection, and the unit is designed to mount in a standard panel or enclosure with a 70 mm depth, 76.2 mm width, and 130 mm height. ## Integration and deployment The 3VA1150-5EF36-0HC0 fits into a standard panel cutout for SENTRON 3VA frame sizes; the 76.2 mm width matches the 3-pole footprint common across the series, so a panel designed for a 3VA1110 variant will accept this unit without rewiring, provided the busbar and lug kit accommodate the 50 A rating.","metaTitle":"Siemens 3VA1150-5EF36-0HC0 SENTRON MCCB, 50 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA1150-5EF36-0HC0 molded case circuit breaker, 3-pole, 50 A rated, 187 kA at 240 V.
