Siemens 3VA2063-6KP46-0AA0 — SENTRON MCCB with ETU850 Release
Its ETU850 electronic overcurrent release provides adjustable protection curves for line distribution, not just thermal-magnetic fixed trip. Communication function is built in, so it can report status and trip events to a PLC or BMS over the plant network.
This MCCB delivers 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V. For a 480 V panel, the 187 kA figure gives you headroom for high-fault service entrances. The minimum rated current is 95 A, and the maximum is 756 A, which means the ETU850 release can be adjusted to protect conductors sized anywhere in that band.
Dimensions: 181 mm height, 140 mm width, 86 mm depth. Front IP40 protection means it's suitable for dry indoor panels only — no washdown environments.
The SENTRON 3VA series carries UL 489, CSA C22.2 No. 5, and IEC 60947-2 certifications as standard. RoHS and REACH declarations are included in the Siemens documentation package.
