The breaker includes an undervoltage release and a ground-fault monitoring function using summation current formation on L+N conductors, so it can serve as both a line protector and a personnel-safety device in a single enclosure. ## Panel Fit & Integration — 4-Pole Footprint with Communication A communication function is built in, so it can report status and trip events to a higher-level control system without an external add-on module. Maximum power loss is 5.5 W, which keeps internal panel temperature rise manageable even in a densely populated enclosure. ## Ratings That Matter for Selectivity and Coordination The adjustable thermal-magnetic trip range spans from a minimum of 95 A to a maximum of 756 A, with an initial value of 16 A — this lets the breaker coordinate with downstream feeders while maintaining full short-circuit protection. At 690 V the interrupting rating drops to 3 kA, so this breaker is best applied on 240–500 V systems where the high kA ratings are available; for 690 V applications a different frame or series would be needed.","metaTitle":"Siemens 3VA2063-7KQ42-0DA0 SENTRON MCCB, 63 A, 4-Pole, 330 k","metaDescription":"Siemens SENTRON 3VA2063-7KQ42-0DA0 molded case circuit breaker, 63 A, 4-pole, interrupting 330 kA at 240 V.
