Techna Contactors

<p>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).</p>

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
