The 500 A rating holds from 40 °C through 50 °C; above that, derate linearly to 410 A at 70 °C. If you need remote signaling or shunt-trip capability, the 3VA2 accessory platform accepts those add-ons without changing the base breaker.","metaTitle":"Siemens 3VA2450-8HK32-0AA0 SENTRON MCCB, 500 A, 3-Pole, 440","metaDescription":"Siemens SENTRON 3VA2450-8HK32-0AA0 molded case circuit breaker, 500 A continuous, 3-pole, ETU340 release.
