The 3-pole design handles three-phase circuits, and the 110 mm depth fits standard MCCB mounting footprints in most switchboards. Breaking capacity steps down with voltage: 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. Power loss is 96 W maximum at rated current, which adds to the panel heat load. A communication function is built in, so it can report status to a BMS or PLC without an add-on module.","metaTitle":"Siemens 3VA2340-6KP32-0AJ0 SENTRON MCCB, 400 A, 3-Pole, 242","metaDescription":"Siemens SENTRON 3VA2340-6KP32-0AJ0 molded case circuit breaker, 400 A continuous, 3-pole, 242 kA at 240 V.
