In Microelettrica, we design, manufacture and sell a complete range of environment-friendly disconnectors for railway rolling stock and fixed applications. Our worldwide experience of several years guarantees a very high reliability and low maintenance of our products. High performances are achieved through a strongly optimized design, which ensures a robust dimensioning of components and reduced weight and costs.

Power converter, traction propulsion equipment, e-bus and charging stations are the typical applications of our power disconnectors for the railway industry (IEC60077 & IEC61992).

Considering standard versions as well as customized solution, our disconnectors represent the widest portfolio on the market, supporting the “just enough features” approach.

The LTK, LTHM/P-U/D, LTMP,LTRM, LTPD/LTSD and LTWS lines are designed to withstand:

  • typical Shock and Vibration profile of on-board applications according to category 1 – Class B (IEC61373);
  • growing short circuit current occurring in modern railway net.


The following tables help identify the disconnector configuration that can satisfy the specific requirements of each application.
