Pre-Configured Matching Unit (PCMU)

The ideal solution to risk and reducing costs

The PCMU represents the best choice to replace ABB legacy relays. It ensures a reliable, seamless upgrade due to the risk reduction only a wire-like solution can provide. It also offers the lowest possible cost of installation in the market by using the existing wiring and connecting it to the wire-like terminals. Additionally the time to update drawings after installation is virtually eliminated since no changes in wiring are required.
