Rated for 242 kA at 240 V and 187 kA at 415 V / 440 V, this MCCB handles high-fault utility feeds and transformer secondaries. At 500 V it still delivers 121 kA; at 690 V the rating drops to 7.5 kA — adequate for most 690 V motor circuits but not for high-fault 690 V buswork. Above that, derate linearly: 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C. For a 400 A panel in a 55 °C enclosure, plan for 375 A maximum or add ventilation. ## Trip unit and auxiliary complement Electronic trip unit adjustable from 600 A to 4 000 A (instantaneous) with a trip indicator. Line protection design (not motor protection) with communication function and other measurement function onboard. No ground-fault monitoring version fitted.","metaTitle":"Siemens 3VA2340-6KP32-0BH0 SENTRON MCCB, 400 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2340-6KP32-0BH0 molded case circuit breaker, 400 A continuous, 3-pole, 242 kA at 240 V.
