That thermal profile matters when you pack breakers into a warm enclosure; you don't lose headroom until the ambient hits 55 °C. The limited short-time rating is 6 kA for 1 s, which supports selective coordination downstream. Dimensions are 138 mm wide, 248 mm high, 110 mm deep — a standard 3-pole MCCB footprint for the SENTRON 3VA2 frame. No undervoltage release or shunt trip fitted as-delivered; those are add-on accessories.","metaTitle":"Siemens 3VA2450-0MN32-0AA0 SENTRON MCCB, 500 A, 3-Pole, ETU3","metaDescription":"Siemens 3VA2450-0MN32-0AA0 SENTRON molded case circuit breaker, 500 A continuous, 440 kA at 415 V, 3-pole, ETU350M electronic trip unit, motor protection design.
