Breaking capacity is 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 15.3 kA at 690 V. The basic switch variant is 3VA2450-7MN32-0AA0; this order code adds the shunt trip release. No auxiliary switch is included, so if you need a status contact for the PLC, you'll add one separately.","metaTitle":"Siemens 3VA2450-7MN32-0KA0 SENTRON MCCB, 500 A, 3-Pole, Moto","metaDescription":"Siemens 3VA2450-7MN32-0KA0 SENTRON molded case circuit breaker, 500 A, 3-pole, motor protection design, 330 kA at 240 V.
