Breaking capacity runs 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V, which covers most industrial distribution panels and motor branch circuits in North American and European voltage systems. The 50 A rating holds flat from 40 °C through 50 °C ambient; above that it derates to 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C — relevant if you are packing this into a high-density enclosure with limited airflow. Dimensions are 70 mm deep, 76.2 mm wide, and 130 mm tall — a compact 3-pole footprint that fits standard DIN-rail or panel-mount enclosures. The 76.2 mm width (roughly 3 inches) matches the typical 3-pole MCCB slot in a distribution board. The 50 A TM240 release gives a fixed thermal pickup at roughly 1.05× to 1.25× Iu and a magnetic trip threshold at 240 A (4.8× Iu for the TM240 designation). If you are coordinating with a 3VA1112-5EF32-0CA0 or similar sibling, the key difference is the frame size and release type — this 3VA1150 uses a 50 A frame with TM240, while the 3VA1112 uses a 125 A frame with a different electronic or thermal-magnetic curve. Do not assume drop-in interchange without checking the mounting hole pattern and busbar spacing.","metaTitle":"Siemens 3VA1150-3EF36-0BA0 SENTRON MCCB, 50 A, 3-Pole, TM240","metaDescription":"Siemens 3VA1150-3EF36-0BA0 SENTRON molded case circuit breaker, 50 A rated continuous current, 3-pole, TM240 release, 75.6 kA at 240 V.
