That makes it a straight line-protection breaker, not a motor-protection or adjustable version; you spec it for feeder or distribution circuits where the load current is known and stable. The UVR is the design-of-auxiliary-release type, so it's factory-integrated, not a field-add accessory. Breaking capacity is voltage-dependent: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V. At 415 V — common for three-phase distribution in many markets — the 32 kA rating covers most industrial transformer-fed fault levels. The 690 V figure (7.5 kA) is useful for mining or marine applications where the line-to-line voltage is higher. The breaker holds its full 63 A rating from 40 °C up to 50 °C, then derates linearly: 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C. Maximum power loss is 19.8 W at rated load. That's moderate for a 63 A 4-pole MCCB — expect some heat rise inside the enclosure, but it won't drive a ventilation requirement unless the panel is densely populated with other high-loss devices.","metaTitle":"Siemens 3VA1063-2ED42-0BA0 SENTRON MCCB, 63 A, 4-Pole, UVR","metaDescription":"Siemens SENTRON 3VA1063-2ED42-0BA0 molded case circuit breaker, 63 A at 40 °C, 4-pole, TM210 release, undervoltage release.

The UVR trips the breaker when supply voltage drops below its dropout threshold, common for emergency-stop and undervoltage protection schemes."},{"question":"Where can I buy 3VA1063-2ED42-0BA0 and how is it quoted?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution.

However, the 3VA1063 is a higher-current frame (63 A vs the 3VA1010's lower rating) and has a different overcurrent release (TM210 vs whatever the 3VA1010 carries). Check the busbar ampacity and the release curve before swapping — the panel's thermal and magnetic coordination may need re-verification."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1063-2ED42-0BA0","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/3VA1063-2ED42-0BA0 when reusing this data.
