Rolling stock applications necessitate compliance to national and international standards tailored to railway environments. In order to improve reliability and durability, most railway applications employ specific connection methods, such as ring-tongue termination.

Coil surge suppression is also popular among rail applications. ABB's AF Series contactors are equipped with integral surge suppression in the form of a free-wheel diode, eliminating the need for additional accessories. AF Series devices are also immune to short time voltage interruption (or voltage dips) up to 20 ms.

Contactors and contactor relays are used in versatile rolling stock applications:
  • Lighting
  • Heating
  • Braking
  • Air conditioning
  • Ventilation
  • Door control
Requirements of railway applications
  • Control networks typically utilizing DC (battery source) with wide voltage ranges: - 0.7 Uc...1.25 Uc (Operating limits included as Uc)
  • Wide temperature range: -40°C...+70°C
  • Shock & vibration withstand
  • Fire-retardant / low smoke materials required
