Original ABB 500TRM02 1MRB150011R1 transformer module for REB500 protection system, CT/VT signal isolation spare part.

Product Overview

500TRM02 1MRB150011R1 is TRM02 transformer module for ABB REB500 busbar protection system. It converts and isolates high‑level CT and VT current‑voltage signals from primary power equipment into low‑level analog signals for protection unit digital processing. It provides high‑voltage isolation, supports sub‑cycle fast sampling for busbar protection, industrial‑grade hardware, widely used in power plant and high‑voltage substation control cabinets.
