CONTACTORS ELECTRO-MAGNETIC

CONTACTORS ELECTRO-MAGNETIC

for Traction Vehicles

Electromagnetic Contactor is a single pole heavy duty contactor designed to be used on traction vehicles. In order to work efficiently both AC and DC circuits, the contactors are equipped with arc blow-out circuit.

  • Used for Higher voltage, upto 3000V and 50A AC/DC application. Having single pole normally open contacts.
  • Compact and space saving wall mounting.
  • Low maintenance and reliable operations under extreme condition.
  • Contact movement designed for self cleaning action.
  • Contacts are easily inspected and replaced.
  • Independent of polarity.
  • Arc extinguisher helps to break down the arc voltage and to cool the arc effectively.
  • Operating coil designed for voltage tolerance of -30% to +25%.
  • All non metallic components are of fire retardant self –extinguishing materials.
  • Option of upto 4 (NO or NC) auxiliary contacts, customization possible.
  • Sturdy structure and a long mechanical life (over 5 million operations).
