Thermal derating is published from 40 °C to 70 °C: the breaker holds full 400 A up to 50 °C, then drops to 385 A at 55 °C, 370 A at 60 °C, 355 A at 65 °C, and 340 A at 70 °C — essential for sizing in warm enclosures or near heat sources. The breaker measures 110 mm deep, 138 mm wide, and 248 mm tall — fits standard MCCB panel cutouts and busbar spacing for 3-pole 400 A frames. It includes a factory-installed shunt trip (STL) release for remote tripping via a control voltage, but no auxiliary switch or ground-fault module — those are add-on options if needed. The base switch variant is 3VA2340-7HL32-0AA0; the -0JA0 suffix adds the shunt trip.","metaTitle":"Siemens 3VA2340-7HL32-0JA0 SENTRON MCCB, 400 A, 3-Pole, Shun","metaDescription":"Siemens 3VA2340-7HL32-0JA0 SENTRON molded case circuit breaker, 400 A continuous, 3-pole, 110 mm depth, 138 mm width.
