Above 50 °C the rating steps down to 313 A at 55 °C, 306 A at 60 °C, 299 A at 65 °C, and 292 A at 70 °C. That thermal curve means the breaker holds its full 320 A in most standard panel environments; only tight enclosures pushing internal ambient past 50 °C require a down-rate check. Breaking capacity is the headline number here: 220 kA at 240 V, 154 kA at 415 V and 440 V, 121 kA at 500 V, and 17 kA at 690 V. The 17 kA at 690 V still clears most industrial 690 V systems. The TM120M overcurrent release is a fixed thermal-magnetic design with adjustable magnetic trip — li min 2,240 A, li max 4,480 A. That gives a magnetic pickup range of 7x to 14x the 320 A frame rating, which is typical for motor-starting inrush or transformer magnetizing current without nuisance tripping. No ground-fault monitoring, no phase-failure detection, no communication — this is a straight thermal-magnetic MCCB for standard feeder or motor-circuit protection. Dimensions: 248 mm height, 138 mm width, 110 mm depth. Power loss is 80.1 W maximum. In a multi-breaker lineup, that heat adds up — account for it in the enclosure thermal calculation. The design accepts an optional motor drive (Product Extension Optional Motor Drive = Yes), so remote switching or automatic transfer schemes are possible with the add-on accessory. Lifecycle stage is marked as current — meaning Siemens still produces this order code, and it has not been announced for phase-out. No successor code is listed, which is consistent with an active catalog item. Those numbers confirm suitability for most industrial environments outside of extreme cold-storage or high-heat foundry applications.","metaTitle":"Siemens 3VA1332-6MH32-0AA0 SENTRON MCCB, 320 A, 3-Pole, 220","metaDescription":"Siemens SENTRON 3VA1332-6MH32-0AA0 molded case circuit breaker, 320 A continuous, 3-pole, 220 kA at 240 V.
