The undervoltage release adds a coil draw; confirm the control transformer sizing if you're adding this to an existing panel with other UVR coils. The auxiliary switches (2 HQ) occupy the same physical space; no extra side-mount bracket needed. ## Selectivity & coordination With 75.6 kA at 240 V and 52.5 kA at 415 V, this breaker provides strong selectivity downstream of a larger MCCB or upstream of miniature breakers. The undervoltage release is factory-integrated — no field add-on module needed.","metaTitle":"Siemens 3VA1063-3ED42-0CC0 SENTRON MCCB, 63 A, 75.6 kA","metaDescription":"Siemens SENTRON 3VA1063-3ED42-0CC0 molded case circuit breaker, 63 A at 40 °C, 75.6 kA at 240 V, 4-pole with undervoltage release.
