For the panel builder: the 76.2 mm width (3 in) and 70 mm depth (2.76 in) fit standard 3-pole MCCB cutouts; the 19.8 W max power loss at rated load means you should account for that heat in the enclosure's thermal budget, especially if the breaker is enclosed with other dissipating devices. Rated current holds flat at 63 A from 40 °C through 50 °C, then derates to 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C. Breaking capacity varies with system voltage: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V. ## Built-in accessories and design The trip indicator is present, so you get a visual flag on the breaker face after a fault trip — useful for troubleshooting without opening the panel. Designed for line protection (not feeder or motor protection), meaning it's optimized for cable and busbar protection in distribution boards. ## Physical integration The 3-pole footprint matches standard Siemens 3VA1 panel cutouts and busbar connections.","metaTitle":"Siemens 3VA1163-5ED32-0BF0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens 3VA1163-5ED32-0BF0 SENTRON molded case circuit breaker, 63 A rated at 40 °C, 3-pole, 187 kA breaking capacity at 240 V.

The 3VA1110-5ED36-0AC0 is a 100 A frame; this 63 A breaker fits the same footprint, but verify the busbar ampacity and the upstream protection coordination — the lower continuous rating is fine as long as the panel's bus is rated for the load."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1163-5ED32-0BF0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3VA1163-5ED32-0BF0 when reusing this data.
