Techna Contactors

Techna Brand: Techna

This Techna Ktec range of contactors allow switching of high current/power using low current control signals applied to the contactor coil (effectively a high power relay).

  • Available with 24V AC or 240V AC control coils.
  • Some models available with 24V DC control coils
  • Available in 3 pole + auxiliary contact.
  • Auxiliary contacts may be normally open (auxiliary circuit is off when contactor is off) or normally closed (auxiliary circuit is on when contactor is off).
  • Auxiliary contacts allow the connection of signalling circuits giving positive feedback of the contactor being on or off.
  • Available in 4 pole without auxiliary contact
  • Rated electrical life 1.2 million cycles at stated power ratings.
  • Approvals UL recognised and/or Listed (depending upon model) CSA certified, TUV certified, CE and RoHS
  • AC3 ratings apply to 3 phase inductive loads (e.g. motors)
  • AC1 ratings are for purely resistive loads
