That's a real panel-space saver. Dimensions are 248 mm high by 138 mm wide by 110 mm deep — it'll fit a standard MCCB slot in most SENTRON or third-party distribution panels. No derating up to 50 °C at full 400 A, which is solid for a warm enclosure. That thermal curve is what you check when the panel sits next to a furnace line or in a non-climate-controlled electrical room.","metaTitle":"Siemens 3VA2340-5KP32-0CL0 SENTRON MCCB, 400 A, 3-Pole, 121","metaDescription":"Siemens 3VA2340-5KP32-0CL0 SENTRON molded case circuit breaker, 400 A continuous, 3-pole, 121 kA breaking capacity at 415 V.
