Its interrupting rating hits 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at both 500 V and 690 V — figures that give strong selectivity headroom for high-fault installations like transformer secondaries or large motor control centers. The TM220 overcurrent release combines a thermal-magnetic trip with fixed settings, so no field adjustment of the magnetic pickup — the curve is factory-set for line protection duty. ## Integration into the enclosure The 3VA1150-6EE32-0AA0 measures 130 mm high, 76.2 mm wide, and 70 mm deep — a 3-pole footprint that fits standard Siemens SENTRON mounting bases and busbar systems. Maximum power loss is 14.6 W, so ventilation or spacing from heat-sensitive components should be considered in a sealed enclosure.","metaTitle":"Siemens 3VA1150-6EE32-0AA0 SENTRON MCCB, 50 A, 220 kA at 240","metaDescription":"Siemens SENTRON 3VA1150-6EE32-0AA0 molded case circuit breaker, 3-pole, 50 A rated at 40 °C, 220 kA breaking capacity at 240 V.
