Siemens 3VA2340-6JP32-0JL0 SENTRON MCCB, 400 A, 242 kA at 24

The Siemens 3VA2340-6JP32-0JL0 is a SENTRON molded case circuit breaker rated for 400 A continuous current at 40 °C, with a maximum interrupting capacity of 242 kA at 240 V — that figure drops to 187 kA at 415 V and 440 V, then 121 kA at 500 V, and 7.5 kA at 690 V. The 400 A rating holds flat from 40 °C through 50 °C; above that it derates linearly to 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C. Physical footprint: 138 mm wide, 248 mm tall, 110 mm deep. The 3-pole frame fits standard panel layouts for SENTRON 3VA2 breakers. No undervoltage release is fitted on this variant, and no ground-fault monitoring module is included — those are separate add-ons if your application requires them.
