ER+TH-18/x+FAN resistors with internal thermostat and fan. Technical<br />

data<br />

The independent resistors whose reference is ER+TH-18/+FAN are external<br />

electrical resistors that can also be used with power supplies and<br />

compact drives that have an internal thermostat and a single-phase 220 V<br />

AC cooling fan.<br />

* To maintain a sealing protection of IP 65, the surface temperature of the<br />

resistor must not exceed 200 °C / 392 °F.<br />

WARNING. Careful with the surface of these resistors. Remember that its<br />

temperature may exceed 300 °C (572 °F).<br />
