IP67 with AUMA 3-phase AC motor
For special motors, differing enclosure protection is possible
Standard:Enclosure protection according to
EN 60529
●
IP68 with AUMA 3-phase AC motor
●
DS terminal compartment additionally sealed against interior of actuator (double
sealed)
Option:
According to AUMA definition, enclosure protection IP68 meets the following requirements:
●
Depth of water: maximum 8 m head of water
●
Duration of continuous immersion in water: Max. 96 hours
●
Up to 10 operations during continuous immersion
●
Modulating duty is not possible during continuous immersion.
For exact version, refer to actuator name plate.
Pollution degree 4 (when closed), pollution degree 2 (internal)Pollution degree according to IEC
60664-1
2 g, from 10 to 200 Hz (for actuators in AUMA NORM version)
1 g, von 10 bis 200 Hz (for actuators with AM or AC integral controls)
Resistant to vibration during start-up or for failures of the plant. However, a fatigue strength may not be
derived from this. Indiations apply to actuators with AUMA 3-phase AC motor and AUMA plug/socket
connector.They are not valid in combination with gearboxes.
Vibration resistance according to
IEC 60068-2-6
KS: Suitable for use in areas with high salinity, almost permanent condensation, and high
pollution.
Standard:Corrosion protection
KX: Suitable for use in areas with extremely high salinity, permanent condensation, and
high pollution.
Option:
KX-G : same as KX, however aluminium-free version (outer parts)
