TeSys F

Contactors to control motors up to 1000 A (500 kW / 440 V)

Part of TeSys

TeSys F is a range of high current contactors from 115 A to 1000 A designed for AC-3 applications and from 200 A to 2600 A for AC-1 applications.

TeSys F
  • Features

    TeSys F series of contactors are specifically designed for the most demanding motor and power switching applications.

    TeSys F

    • 2 pole (400 A, 500 A & 630 A), 3 pole (115 – 2600 A) & 4 pole (115 A – 780 A) contactors
    • Pre-assembled star-delta motor starters (185-375 kW/440V AC), 3 pole AC-3 reversing contactors (115 A – 265 A) & 4 pole AC-1 change-over contactors (200-350 A)
    • Separate components and kits available for customer assembly of motor starters, reversing and change-over contactor solutions
    • Wide range of AC (40-400 Hz) and DC operating coils
    • Terminal connections suitable for connecting bus bars & cables
    • Wide range of common accessories to improve flexibility, functionality & safety
    • Complemented by Class10/20 LR9F type electronic thermal over-load relays and TeSys GV7-R circuit breaker for motor starter solutions
    • Suitable for switching of motors, lighting, heating, capacitors, auto-transformer starting, rotor circuits of slip-ring motors, etc.

    • AC-3 range
      - For motor applications, up to 670 kW / 440 V
      - Switching of motors in normal or severe service conditions
    • AC-1 range
      - For switching applications 200 A to 2600 A
      - Dedicated AC-1 range of contactors from 1200 to 2600 A for power switching applications.

    TeSys FG range

    • 150 to 630 A, 3 pole contactors
    • Shockproof contactors for AC & DC applications
    • Avoid accidental closing of contactor due to severe mechanical shocks
    • Mechanically locked in “open” position when electromagnet is not energized

    TeSys CR1 F

    • Magnetic latching contactors
    • 150 to 630 A in 3 & 4 pole versions
    • Suitable for applications requiring contactors in ON condition for much longer periods


    TeSys F is a versatile range of contactors with large installed base, offering multiple benefits to the users.

    • TeSys F offers high performance in motor control & power switching applications
    • Proven reliability with high mechanical and electrical durability
    • Combined with the LR9 electronic relay or GV7 motor circuit breaker, AC-3 contactors are the ideal motor starters offering quick & simple selection
