Aprotection systems are more important than ever.
To ensure service continuity, Thytronic has introduced XMR-L,
a high-performance, multifunction relay designed to extend
differential protection to MV line applications.

Founded in Italy, Thytronic specialises in protection, control,
automation and monitoring systems for electrical power grids.
The company is renowned for its reliable and innovative solutions
for utilities, industry and critical infrastructures worldwide.
With XMR-L, Thytronic meets the changing challenges of modern
grids by combining cutting-edge technology with proven Thanks to its performance and flexibility, XMR-L is
