DDL9000

Catenary voltage protection up to 3 kV

Protects your catenaries or the power supply rails for direct current electric traction.

Our DDL9000 protection relay facilitates the operation of your railway electrical networks thanks to its protection functions such as [di/dt] and its patented parallel line management version, or its high capacity for recording faults and events.

Its embedded web server and its touch screen HMI, allow you to calmly approach the future of your railway infrastructures.
