That matters when the breaker shares an enclosure with other heat sources — plan the thermal budget accordingly. The 3-pole footprint is the same as other SENTRON 3VA frames in this class, so panel cutouts and busbar layouts carry over.","metaTitle":"Siemens 3VA1340-5EF32-0DJ0 SENTRON MCCB, 400 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA1340-5EF32-0DJ0 molded case circuit breaker, 400 A at 40 °C, 3-pole, 187 kA interrupting at 240 V.
