EX AF B 001 2 U0 N 000/ AEX24-1-S/U
15 Nm explosion proof spring return actuator. On-Off control. Rotation 95°
Features
EEx d IIC T6
Damper actuator according to the European Standards EN 50014 EN 50018,
flameproof enclosure tested by CESI. EEx d llC T6.
The actuator moves the damper to its working position while tensioning the return
spring until it is powered. If the power supply is interrupted the spring moves the damper back to its safe position. The actuator is overload protected and can be mechanically stopped in any position.
The actuator can be mounted directly on the damper shaft if square, 12 x 12 mm or
10 x 10 mm (adaptor included); several mounting brackets are available for applications where the actuator cannot be directly coupled to the damper shaft.
The cable glands are fit for cable diameters from 8 to 10,5 mm.
