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.
Under the heaviest load at the highest temperature the
capability is up to 3,600 per hour. Favourable load conditions
enable unrestricted starts per hour.
Option temperatures use different actuator components,
please specify temperature requirement. Hazardous area
approvals for other country standards are available; please
contact Rotork.
CMA Range actuators are built in accordance with the
following standards:
