The 3-pole frame is built for selective coordination in motor control centers and distribution panels, with an interrupting capacity of 330 kA at 240 V AC and 242 kA at 415 V AC — the 690 V rating drops to 15.3 kA, so verify the available fault current at the point of installation. The MCCB measures 248 mm high by 138 mm wide by 110 mm deep, fitting standard panel-mount cutouts for 3-pole SENTRON 3VA2 frames. The 6 kA limited-to-1-second rating is a short-time withstand figure for selective coordination downstream of a larger feeder — useful when setting the trip curve for motor starting inrush.","metaTitle":"Siemens 3VA2450-7MN32-0KC0 SENTRON MCCB, 500 A, 3-Pole Motor","metaDescription":"Siemens 3VA2450-7MN32-0KC0 SENTRON molded case circuit breaker, 500 A at 40 °C, 3-pole, motor protection design with shunt trip and phase failure detection.
