Four-pole construction with line-protection firmware (ETU860 electronic trip unit), carrying a 330 kA interrupting capacity at 240 V and 242 kA at 415 V — figures that place it in the high-fault tier for main or feeder breakers in industrial distribution. The ETU860 release supports adjustable N-conductor protection (OFF, 40 % to 160 % of the phase setting) and ground-fault monitoring via summation current formation on L + N — a combination that covers both overload and earth-leakage in a single device, eliminating a separate GFCI module. Communication function is onboard, enabling remote trip indication, load monitoring, and selective coordination from a PLC or BMS. ## Integration — Panel Fit and Mounting Dimensions are 181 mm height, 140 mm width, 86 mm depth — a standard 3VA2 frame size that bolts directly into the SENTRON mounting plate or a DIN-rail adapter kit. Power loss is 5.4 W maximum at rated current — low enough that ventilation in a typical IP54 enclosure is adequate; no forced-air cooling needed for a single unit. The 20 000 latching endurance cycles cover frequent switching applications like capacitor-bank or motor-feeder duty.","metaTitle":"Siemens 3VA2063-7KQ46-0AA0 SENTRON MCCB, 63 A, 4-Pole, ETU86","metaDescription":"Siemens 3VA2063-7KQ46-0AA0 SENTRON molded case circuit breaker, 63 A continuous, 4-pole, ETU860 electronic trip unit, 330 kA at 240 V.
