The 3VA1063-3ED32-0AC0 is a SENTRON molded case circuit breaker rated 63 A continuous at 40 °C, with no derating needed up to 50 °C — at 55 °C it still carries 62 A, and at 70 °C it holds 58 A. That thermal curve means this MCCB handles full load in a warm enclosure without tripping prematurely. Interrupting capacity hits 75.6 kA at 240 V and 52.5 kA at 415 V — figures that cover high-fault commercial and industrial service entrances. The 3-pole format and 70 x 76.2 x 130 mm footprint fit standard DIN-rail or panel-mount layouts — no special adapter needed for a typical MCC bucket.
Integration notes
No undervoltage release or shunt trip is fitted from the factory — those are add-on accessories if needed for emergency-off or undervoltage protection schemes. Maximum power loss is 17.3 W, so in a densely packed panel the heat load is manageable but not negligible — account for it in the thermal budget if the MCCB sits beside other high-draw devices.
