The thermal overload relays TI 16C-30C cover the range from 0.13-32 Amp and protect squirrel cage motors of up to 15 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.
