Non-Hazardous and Hazardous Certified Enclosures
All CMA actuator hazardous and non-hazardous area
enclosures are watertight to IP66, IP67 and NEMA 4.
CMA actuators are available with the following enclosure
types for which the ambient working temperature ranges
are stated.
The limits of frequency of operation are a function of the load
on the actuator and the ambient temperature.
3. Approvals
Under the heaviest load at the highest temperature the
capability would be not less than 2,000 starts in one hour, in
favorable load conditions the number of starts per hour would
be infinite.
Where option temperatures are indicated, changes to
some actuator components are required and therefore the
temperature requirement must be specified. Hazardous area
approvals for other country standards are available; please
contact Rotork.
CMA range actuators are built in accordance with the
following standards:
3.3 Environmental Conditions
a) Altitude up to 5000 meters
b CMA adheres to requirements consistent with Overvoltage Category II
c) The CMA adheres to the requirements consistent with a Pollution Degree of 2
