Thermal overload relays, type TI 9C / 12C

Protecting squirrel cage motors

  • For use with mini contactors CI 4
  • Compact design
  • Stop/reset button
  • Manual/automatic reset function
  • Test trip function
  • Double scale for direct start or Y-∆ start
  • Galvanically isolated signal contacts
  • Single phase failure protection
The thermal overload relays TI 9C-12C cover the range from 0.13 -12 Amp and protect squirrel cage motors of up to 5.5 kW against overload.

The phase failure function accelerates the trip function by three phase run if a phase drop-out occurs. This is particularly important for delta connected motors.
