At 415 V and 440 V it still holds 187 kA, and at 500 V it delivers 121 kA; only at 690 V does the rating drop to 7.5 kA, so verify your system voltage against that curve. Above that, it steps down: 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C. If your enclosure runs hot, size the breaker for the actual ambient, not the nameplate 400 A. This version includes a communication function and an undervoltage release, plus a full auxiliary switch complement: two auxiliary switches, one trip alarm switch, and one electrical alarm switch HQ. The trip indicator gives a local visual flag. The basic switch is order code 3VA2340-6JP32-0AA0. The breaker measures 138 mm wide, 248 mm tall, and 110 mm deep. The 138 mm width and 248 mm height match the standard SENTRON 3VA frame footprint, so it drops into existing cutouts without re-drilling. Rated for line protection, this MCCB is designed for main or feeder duty in distribution panels. The 3-pole form factor suits three-phase systems.","metaTitle":"Siemens 3VA2340-6JP32-0BL0 SENTRON MCCB, 400 A, 3-Pole, 242","metaDescription":"Siemens SENTRON 3VA2340-6JP32-0BL0 molded case circuit breaker, 400 A continuous, 3-pole, 242 kA at 240 V.
