Breaking capacity reaches 330 kA at 240 V AC, dropping to 242 kA at 415/440 V and 187 kA at 500 V — sufficient for high-fault utility feeds or transformer secondaries. At 690 V the rating is 15.3 kA, so verify coordination if applied on 690 V systems. ## Thermal management and operating range Maximum power loss is 101.5 W — account for this heat in a sealed enclosure; the breaker is rated for operation from -25 °C to 70 °C ambient, with storage from -40 °C to 80 °C. The short-time withstand rating is 6 kA limited to 1 second — relevant for selectivity studies where downstream breakers clear faster than the MCCB's thermal trip. The base switch variant is 3VA2450-7MN32-0AA0; this -0CC0 suffix adds the undervoltage release and two auxiliary switches HQ (high-auxiliary count). No communication function is fitted on this variant.","metaTitle":"Siemens 3VA2450-7MN32-0CC0 SENTRON MCCB, 500 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2450-7MN32-0CC0 molded case circuit breaker, 500 A at 40°C, 3-pole, motor protection design with undervoltage release.
