That interrupting capacity of 75.6 kA at 240 V and 52.5 kA at 415 V tells you this breaker can clear a fault up to those levels without welding its contacts or rupturing the case, which is the difference between a contained trip and a panel fire. The 3-pole design and line-protection profile make it a straight fit for feeder or branch circuits in a distribution panel, not for motor-starting duty where you'd want an adjustable magnetic trip. ## Integration notes The 76.2 mm width (3 in) and 130 mm height (5.12 in) fit a standard 3-pole MCCB slot in most Siemens or third-party distribution boards. Depth of 70 mm (2.76 in) leaves clearance for rear-connected busbars or cable lugs. ## Selectivity and coordination The TM210 release gives a fixed time-current curve. For a 50 A feeder, pair it with branch breakers to achieve full discrimination up to the short-circuit region.","metaTitle":"Siemens 3VA1150-3ED32-0AA0 SENTRON MCCB, 50 A, 3-Pole, 75.6","metaDescription":"Siemens 3VA1150-3ED32-0AA0 SENTRON molded case circuit breaker, 50 A rated at 40 °C, 3-pole, 75.6 kA interrupting at 240 V.
