AC1 Duty Contactors 3TK5
When contactors are not required to make or break current but only carry the current, the contactors
can be used to its full AC1 rating. Siemens 3TK5 AC1 duty contactors can be offered in such cases.
Application
3TK5 AC1 duty contactors are widely used in sugar mills, DC
drives and changeover applications. Also they can be offered for
the applications like switching resistive loads, battery charging etc
where the AC1 rating of the contactor is suitable.
Standards
3TK5 contactors conform to IS/IEC 60947-4-1. They also carry the
CE mark.
Range
3TK5 AC1 duty air break contactors are available from 190A (AC1)
to 500A (AC1) in 3 pole version.
Benefits and features
High performance
• No duration upto 55°C
SICOP contactors are suitable for operation in service
temperature upto 55°C without derating. This avoids selection
of higher rated contactor, thereby reducing cost.
• Long Life
Superior design of current carrying parts, contact system and
the magnet system increases the reliability results into higher
electrical and mechanical endurance.
High reliability
• High insulation voltage and impulse withstand voltage capacity
ensures reliable performance during occasional abnormal
increase in supply voltage.
User friendliness and safety
• Arc Chamber Interlock
It prevents the contactor from switching ON, if the arc chamber
is not fitted properly. Thus avoids accidents to plant and
personnel
• Positively driven contacts
3TF contactors satisfy the conditions for positively driven
operation between the main power contacts and the NC
contacts. NC contacts positively open before the main contact
closes. This is extremely important when power contactors are
used in safety circuits of critical applications.
