Application:

Environment where an explosive atmosphere will probably not be present under normal operating conditions and, if any, this will be for short period of time, that is, an explosive atmosphere may be present accidentally.

The environments are classified as Zone 2, groups IIA, IIB and IIC, and as Zone 22, groups IIA, IIB and IIC. The most common gases included in this classification are: acetone, ammonia, benzene, butane, butanol, buthylic alcohol, ethane, ethanol, acetate of ethyl, gasoline, heptanes, hexanes, natural gas, methanol, oil naphtha, propane, propanol, toluene, esthyrene, solvents in general, acetaldehyde, cyclopropane, diethylic ether, ethane, monoxide of carbon, acetylene, butadiene, oxide of ethane, hydrogen, oxide of propylene and gases containing over 30% of hydrogen.

Standard Features:

Output: 0.12 up to 250kW
Multivoltage– (220-240/380-415//440-460V or 380-415/660-690//440-460V)
Self Ventilated (TEFC)
EFF1 Premium Efficiency
Cast iron frame 63 up to 355M/L
Mounting: B3T
Degree of Protection: IP55
Squirrel cage rotor/Aluminium die cast
Zone 2: class of temperature T3
Zone 22: maximum external surface temperature T 125°C (dust layers up to 5mm)
Stainless steel nameplate AISI 316
Class “F” insulation with T 80K
Continuous duty - S1
Ambient temperature: 40°C , 1000 m.a.s.l.
Regreasing nipples from frame 160 and above
Thermistors 155ºC - 1 per phase
Thermistors 140° C - 1 per phase
Note: If the motor is used at Zone 2 (gas), 155°C PTC is required as it complies with the worse condition for such application. The 140°C PTC may be used as alarm. In case motor is used in areas classified as Zone 22(non-conductive dust), 140°C PTC must be applied, so as to ensure the worse condition is also met under such application.

Classification:

IEC Standard:

Zone 2 (Gas); Group IIC
Zone 22; Group IIC (non-conductive dust)

CENELEC Standard:

Zone 2; Group IIC; Category 3G (Gas)
Zone 22; Group IIC; Category 3D (non-conductive dust)

Note: The classification in Group IIC means that the motor is suitable to operate also in Groups IIA and IIB once Group IIC represents an operating condition worse than Groups IIA and II
