Breaking capacity hits 121 kA at 240 V, 75.6 kA at 415 V, and 52.5 kA at 440 V — numbers that matter for selectivity studies and SCCR headroom in a distribution panel. The 50 A rating holds flat from 40 °C through 50 °C, then derates to 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. The 121 kA at 240 V is the high-fault end; the 75.6 kA at 415 V is the one most European 400 V panels will reference for let-through coordination with downstream MCBs. No undervoltage release, no ground-fault module, no auxiliary contacts on this variant. The shunt trip (STL) is wired separately for remote trip; its order code is 3VA9688-0BL30 if you need a spare or replacement coil. The 70 mm depth and 76.2 mm width fit the SENTRON 3VA family footprint; the 130 mm height is the same across the range. The 3-pole footprint with shunt trip occupies the same cutout as other SENTRON 3VA fixed-breaker variants — if the panel was laid out for a 3VA1110 or 3VA1010, this 3VA1150 drops in without rewiring, provided the lug kit matches the cable size. The shunt trip adds a control wire; the breaker itself has no auxiliary contacts, so remote status indication needs an external block.","metaTitle":"Siemens 3VA1150-4EF36-0HA0 SENTRON MCCB, 50 A, 121 kA at 240","metaDescription":"Siemens 3VA1150-4EF36-0HA0 SENTRON 3-pole molded case circuit breaker, 50 A rated, 121 kA breaking at 240 V.
