TeSys K Miniature Contactors

Available up to 12A for AC3 and 20A for AC1 applications

Part of TeSys

TeSys K miniature contactors and overload relays are available in 3 contactor ratings for the USA market for inductive motor applications up to 12 full-load amps and resistive loads up to 20 amps.

TeSys K Miniature Contactors
  • Features

    TeSys K contactors and overload relays are ideal for general duty applications where small size and reliability are key concerns. The special armature structure design allows all devices and all operating coils, either AC or DC, to have the same physical size and panel footprint for convenience. Devices are available with low consumption DC operating coils for direct connection to PLC circuits.


    • Three contactor ratings for the USA market:
      • K06 rated for 3 HP motors at 480 VAC or 600 VAC.
      • K09 rated for 5 HP motors at 480 VAC or 600 VAC.
      • K12 rated for 7.5 HP motors at 480 VAC or 10 HP at 600 VAC.
    • IP20 finger-safe terminals with both North American and International terminal markings
    • Mountable on 35mm DIN rail or panel mount with screws
    • Available in 3-pole contactor versions with built-in auxiliary contact for holding circuit or 4-pole contactor versions
    • Current rating from 6-12A
    • High-fault short circuit current ratings provide the flexibility to select any component, as long as it meets or exceeds the desired SCCR.
    • Two levels of ratings:
         1. Available at 100 kA on systems with fuses, up to 600 volts
         2. Available at 65 kA on systems with circuit breakers, up to 480 volts
    • Simple to select the right product
    • Easily-installed accessories.
      • 2-pole or 4-pole instantaneous auxiliary contact blocks with screw clamp, slip-on, or spring terminals
      • Transient voltage surge suppressors
      • Electronic 1 to 30 second on-delay timers
    • Four wiring methods to reduce installation time:
      • Captive screw terminals for use with either Phillips or slotted head screwdrivers
      • Slip-on terminals for quick installation of single 1/4" or double 1/8" tabs
      • Terminal pins for soldering the contactor directly to a printed circuit board
      • Spring terminals for extreme-vibration applications
    • Control circuit flexibility

    All versions of the TeSys K-line mini-contactors are available with an AC, DC, or low-consumption DC operating coil. The low-consumption DC coil operating device can be energized by a low level DC signal from a computer or PLC and includes built-in transient suppression.

    • Bimetallic overload relays

    The K-line Class 10 bimetallic overload relays are ambient-compensated and include single-phase sensitivity for phase unbalance and phase loss protection." to "The TeSys K Class 10 bimetallic overload relays are ambient-compensated and include single-phase sensitivity for phase unbalance and phase loss protection. Five pins connect to the contactor load side terminals — three for the power circuit and two for the control circuit — which eliminate customer wiring for the 3-wire control holding circuit.
