Railway Contactors


In Microelettrica, we design, manufacture and sell a complete range of environment-friendly contactors for railway rolling stock and fixed applications. Our experience of several years guarantees installations with very high reliability and low maintenance. High performances are achieved through a strongly optimized design, which ensures a robust dimensioning of components with reduced weight and costs. The electric arc is fully contained inside the arc-chute. 

Our power contactors are suitable for the railway (IEC 60077 & IEC 61992) and energy-intensive industries, as well as for renewable energies and e-mobility (IEC60947-4-1). Typical applications include power converter, traction propulsion equipment, e-bus and charging stations, DC traction power substations and power plants electrical equipment. 

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

We designed LTX, LTHS, LTC and LTHH/LTE/LTP lines to withstand the typical Shock and Vibration profile of on-board applications according to category 1 – Class B (IEC61373). Instead, N Series contactors provide a modular and flexible solution, and address the requirements of fixed applications for railways, heavy industry and energy production. 

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