Product Overview

1VCR000993G0002 is ABB auxiliary power‑supply printed‑circuit‑board assembly, designed as control‑circuit accessory for medium‑voltage vacuum‑contactor units. It converts AC auxiliary‑mains input into multiple stable regulated DC supply rails for internal contactor control‑logic, monitoring‑circuit and interlock‑electronics inside switch‑gear cubicles. Multiple built‑in fault‑protection mechanisms improve reliability under substation‑grid‑disturbance conditions. Surplus and refurbished tested spare board for medium‑voltage switch‑gear‑cabinet maintenance‑projects.

Application Notes

‑ Strict ESD anti‑static handling required during PCB replacement inside energized‑safe switch‑gear environment. ‑ Confirm auxiliary‑mains voltage setting before power‑on. ‑ Verify all DC output rail voltages after board swap‑out. ‑ Typical deployment: MV vacuum‑contactor auxiliary‑power‑board spare‑part stocking.
