Thermal overload relays TI 16C, TI 25C and TI 30C are used with contactors CI 6-30 to give protection of squirrel-cage motors of 0.09 kW to 15 kW.
The relays have single-phase protection, i.e. accelerated release if phase drop-out occurs. This is particularly important for motors with deltaconnected windings.
- Other features of TI 16C/25C/30C:
- manual/automatic reset
- test button
- double scale for direct start or Y/D start
- galvanically isolated signal contact
