That 630 A figure is the maximum uninterrupted current the breaker can carry under standard conditions; at elevated panel temperatures the rating derates linearly — 600 A at 45 °C, 570 A at 50 °C, and down to 450 A at 70 °C. For a panel builder, the derating curve matters more than the headline number: if your enclosure runs at 55 °C, the usable rating is 540 A, not 630 A. The interrupting capacity is equally load-dependent: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V. The ETU850 is a fully electronic, communication-capable trip unit. It supports the Communication Function and Other Measurement Function, meaning it can report current values and trip events over a bus — useful for a plant-wide power monitoring scheme. ## Panel integration — dimensions and mounting The breaker measures 138 mm wide, 248 mm high, and 110 mm deep. The maximum power loss is 162 W, so factor that into your thermal budget if the breaker is enclosed without forced ventilation. As a Siemens SENTRON product, the 3VA2463-5KP32-0AJ0 carries the usual IEC/UL certifications for molded case circuit breakers. The manufacturer provides RoHS and REACH declarations, plus IEC 60947-2 test reports. For an emergency breakdown contractor or a panel builder needing compliance paperwork, these documents are available from Siemens directly or through the distributor at quote time.","metaTitle":"Siemens 3VA2463-5KP32-0AJ0 SENTRON MCCB, 630 A, 3-pole, ETU8","metaDescription":"Siemens SENTRON 3VA2463-5KP32-0AJ0 molded case circuit breaker, 630 A rated, 3-pole, ETU850 trip unit, 187 kA at 240 V.
