The steep drop to 3 kA at 690 V is typical for a 63 A frame — it's not a 690 V main breaker. Front IP40 — sealed against tools and wires over 1 mm, but not washdown. Maximum power loss is 5.4 W. Mounts in a standard distribution panel or MCC bucket; the 4-pole width at 140 mm is wider than a 3-pole unit, so check your busbar and enclosure fill factor before committing the BOM line.","metaTitle":"Siemens 3VA2063-7KP46-0AA0 SENTRON MCCB 4P 63A ETU850 330kA","metaDescription":"Siemens SENTRON 3VA2063-7KP46-0AA0 molded case circuit breaker. 4-pole, 63 A rated, ETU850 electronic trip. 330 kA at 240 V.
