Starting Torque Limiter
Type TCI (Soft Start)
Starting Torque Limiters are designed for the soft
starting of single and tree phase AC motors.
The controller allows smooth starting of all AC
induction motors thus eliminating the damaging
eff ects of high starting torque surges.
The TCI controller is easily installed between a
standard motor starter and the motor, and
features adjustable ramp-up time and initial
torque.
Typical applications are conveyors, fans,
compressors etc.
Features • Ramp-Up time adjustable from 0.5 – 5 sec.
• Initial torque adjustable up to 85%
• Single and three phase operation
• LED Status indication
• Unlimited start/stop operations per hour
• IP20 Protection
• Compact modular design
• DIN rail mountable
• EN 60947-4-2
• CE, CSA, NRTL/C and C-tick
