Issue No: 0EQUIPMENT:
Equipment and systems covered by this Certificate are as follows:
The EMT… series electric actuator is composed of the mechanical transmission compartment and three flameproof enclosures including
an electric control compartment, a motor compartment and a wiring compartment. The whole product meets the requirements of Ex tb also,
and the mechanical transmission compartment is relevant to Ex tb only.
There are four basic sizes of the products, the mechanical transmission compartments and the motor compartments are different according
to the sizes, and the electric control compartment is different in the type EMT4… compared to other types.
Each motor winding is equipped with two thermal protectors.
