ER+TH-18/x+FAN resistors with internal thermostat and fan. Techni-
cal data
The independent resistors whose reference is ER+TH-18/+FAN are ex-
ternal electrical resistors that can also be used with power supplies and
compact drives that have an internal thermostat and a single-phase 220 V
AC cooling fan.
Chapter

* To maintain a sealing protection of IP 65, the surface temperature of the
resistor must not exceed 200 °C / 392 °F.
WARNING. Careful with the surface of these resistors. Remember that its
temperature may exceed 300 °C (572 °F).
