Danfoss Overload Relays
The Danfoss thermal overload relay range TI9 C, TI16 C, TI25 C, TI30 C, TI80 & TI86 are used with the contactor range CI 4 - CI 86 to give protection of squirrel-cage motors.
The Danfoss electronic motor protection relays TI 180E and TI 630E give effective protection of electric motors exposed to thermal overload, phase failure and asymmetrical load.
The selection of a Danfoss thermal overload relay must be based on the motor full load current and the method of starting:
- With direct start range for motor starter is used.
- With star – delta start the range for Y/D starter is used.

| Danfoss Overload Relay - TI 9C-5 047H3130 047H3131 047H3132 047H3133 047H3134 047H3135 047H3136 047H3137 047H3138 047H3139 047H3140 |
The Danfoss thermal overload relay TI 9C-5 is used with minicontactor CI 5 – for protection of squirrel cage motors where compactness is required. The relay have single – phase protection, i.e. accelerated release if phase drop-out occurs.
This is particularly important for motors with delta connected windings.

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.
