Above that it derates: 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C. Dimensions: 248 mm high, 184 mm wide, 110 mm deep. The 184 mm width for a 4-pole frame is standard for this class — it will drop into a panel cutout designed for a SENTRON 3VA2 4-pole without rework.","metaTitle":"3VA2340-6JP42-0AA0 SENTRON MCCB, 400 A, 4-Pole, ETU550","metaDescription":"Siemens SENTRON 3VA2340-6JP42-0AA0 molded case circuit breaker, 400 A continuous, 4-pole, ETU550 release, 242 kA at 240 V.
