It is designed for line protection and includes an undervoltage release and communication function, making it suitable for integration into industrial power distribution panels where high fault current capability and remote monitoring are required. The 400 A continuous rating at 40 °C holds flat through 50 °C (–), then derates to 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C (–). The interrupting ratings span 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 7.5 kA at 690 V (–). The 187 kA at 415 V covers most European industrial service entrance requirements; the drop to 7.5 kA at 690 V means this is not the breaker for a 690 V main — that's a coordination call. The breaker measures 110 mm deep, 138 mm wide, and 248 mm high (–). Maximum power loss is 98.5 W, which should be factored into enclosure thermal calculations — especially if the breaker is grouped with other high-current devices. The auxiliary switch configuration includes two HQ auxiliary switches and an undervoltage release, all factory-installed.","metaTitle":"Siemens 3VA2340-6KP32-0DC0 SENTRON MCCB, 400 A, 3-Pole","metaDescription":"Siemens 3VA2340-6KP32-0DC0 SENTRON molded case circuit breaker, 400 A continuous, 3-pole, 242 kA at 240 V.
