The interrupting capacity is voltage-dependent: 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 — so at typical 480Y/277 V distribution levels you have headroom well above most fault-current studies. The breaker includes a shunt trip (STL) for remote opening, two auxiliary switches plus a trip alarm switch (HQ), and a communication function for integration into a monitored distribution system. ## Thermal derating — don't size by the nameplate alone Above that it derates linearly: 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C. Maximum power loss is 96 W, which factors into enclosure thermal calculations. ## Physical fit — dimensions and mounting The 138 mm width is the same as the 3VA2 frame common to other SENTRON 3-pole MCCBs in this current class, so if you are swapping a 3VA2116-5JP32-0AE0 or similar, check the depth — the 110 mm depth may differ from older frames and could interfere with enclosure doors or busbar shroud clearance.","metaTitle":"Siemens 3VA2340-6KP32-0HH0 SENTRON MCCB, 400 A, 3-Pole, 242","metaDescription":"Siemens SENTRON 3VA2340-6KP32-0HH0 molded case circuit breaker, 400 A continuous, 3-pole, interrupting capacity 242 kA at 240 VAC.
