The full-scale current rating is 400 A, and the initial value for the long-time pickup is 80 A. The trip indicator confirms the breaker has opened on a fault, which saves troubleshooting time on a multi-feeder panel. The design is line-protection (not motor-protection), so it is suited for feeder and main breaker duty rather than individual motor branch circuits.","metaTitle":"Siemens 3VA2440-7JQ32-0BL0 SENTRON MCCB, 400 A, 3-Pole","metaDescription":"Siemens 3VA2440-7JQ32-0BL0 SENTRON molded case circuit breaker, 400 A rated at 40 °C, 3-pole, 330 kA at 240 V.

The 3VA2440 is the 400 A frame and shares the same mounting bolt-hole pattern, so it can drop into a panel originally specified for the 3VA2116 without rewiring the base plate. The auxiliary switch and communication options differ — verify the specific 3VA2116 variant's accessory count before assuming a direct swap."},{"question":"Where can I buy 3VA2440-7JQ32-0BL0?","answer":"This breaker is sourced to order against an RFQ through our industrial automation distribution channel.
