Interrupting capacity is the headline: 187 kA at 240 V AC, 121 kA at both 415 V and 440 V, and 76 kA at 500 V. The 500 A continuous frame means it can feed a large motor control center or a sub-distribution board without needing a fused disconnect upstream. Thermal derating is published: the breaker holds 500 A from 40 °C through 50 °C, then steps down to 488 A at 55 °C, 476 A at 60 °C, 464 A at 65 °C, and 452 A at 70 °C. ## Sourcing & Lifecycle — Active Production, Quoted to Order For a BOM-freeze or panel-shop buying this MCCB in quantity, the active lifecycle means no forced redesign for the foreseeable future. The TM210 release is a standard thermal-magnetic type, widely accepted in IEC 60947-2 installations across Europe, Asia, and the Middle East. ## Dimensions & Panel Fit — 110 mm Depth, 184 mm Width Physical footprint: 248 mm height, 184 mm width, 110 mm depth. The 184 mm width is the critical dimension for DIN-rail or mounting-plate layout — it occupies roughly 7.24 inches of rail space. Depth of 110 mm (4.33 in) means the breaker body projects about 4.3 inches from the mounting surface, which matters when sizing gland plates or rear-panel clearance in shallow enclosures. ## Comparison with 3VA1112-5EE32-0AA0 — Frame Size and Rating Difference The closest functional peer in the SENTRON family is the 3VA1112-5EE32-0AA0, but it is a fundamentally different frame size. The 3VM1450-5GD42-0AA0 is a 500 A frame with 187 kA interrupting capacity; the 3VA1112-5EE32-0AA0 is a smaller 100 A frame with lower interrupting ratings. They are not panel-drop-in interchangeable — the 3VM1450 requires wider bus spacing, larger lug landing area, and more enclosure volume. If your panel was specified around the 3VA1112, the 3VM1450 will not fit without re-engineering the bus bars and enclosure.","metaTitle":"Siemens 3VM1450-5GD42-0AA0 SENTRON MCCB, 500 A, 4-Pole, TM21","metaDescription":"Siemens 3VM1450-5GD42-0AA0 SENTRON molded case circuit breaker, 500 A continuous at 40 °C, 4-pole, TM210 release, 187 kA at 240 V.
