Multilin UR Family Proven, State-of-the-Art Protection & Control Systems

The Universal Relay family of protection and control products are built on a common modular platform. All UR products feature high performance protection, expandable I/O, integrated monitoring and metering, high-speed communications, and extensive programming and configuration capabilities. The UR is the basis of simplified power management for the protection of critical assets.
