Motors for the North American market
Motors with sizes 63 to 200 are available in designs which meet
the NEMA and CSA electrical standard and UL-R.
Ordering information as given in Catalog MD 50.1
NEMA – National Electrical Manufacturing Association
Data on the rating plate:
•
Nominal voltage range
•
Design letter
•
Code letter
• CONT
•
NEMA MG1-12
UL-R – Underwriters Laboratories Inc. listing
The motors are listed for up to 600 V by Underwriters
Laboratories Inc. ("Recognition Mark" = R/C).
Motor voltages up to 600 V are certified according to UL.
"UL Recognition Mark" is included on the rating plate of the
motor.
In addition, the motor is designed to meet the NEMA MG1-12
electrical standard and includes the following data on the rating
plate:
•
Nominal voltage
•
Nominal efficiency
•
Design letter
•
Code letter
• CONT
•
NEMA MG1-12
Externally or internally mounted components such as:
•
Motor protection
•
Heating element
•
Forced ventilation
• Brake
• Encoder
•
Plug connector
are UL-R/C, CSA, or C-US listed or used by manufacturers in
accordance with regulations.
UL-R/C cable glands must be used for the cable entry.
CSA – Canadian Standard Association
The motors are approved for up to 690 V in accordance with the
"Canadian Standard Association" (CSA). Externally or internally
mounted components which are used are listed by CSA or are
used by manufacturers in accordance with regulations. The CSA
mark and the nominal voltage are stamped on the rating plate.
When energy-saving motors are ordered, they also have the
"CSA-E mark" on the rating plate.
Low-voltage motors for the Chinese market
CCC-certified motors, sizes 63 to 71 are available for export to
China.
The "China Energy Label" required for import into China is avail-
able for motors with sizes from 100 to 160.
The motors are marked according to the requirements with CCC,
CEL or both specifications.
Ordering information as given in Catalog MD 50.1
CCC – China Compulsory Certification
"Small power motors" which are exported to China must be cer-
tified up to a nominal power of:
2-pole:
2.2 kW
4-pole:
1.1 kW
6-pole:
0.75 kW
8-pole:
0.55 kW
LA motors requiring certification
are certified by CQC
(China Quality Certification Center)
When ordered, the "CCC (Safety Mark)" logo is stamped
on the rating plate and packaging.
Note:
Chinese customs checks the need for certification of imported
products by means of the commodity code.
The following do not need to be certified:
•
Motors imported to China which have already been installed
in a machine
•
Repair parts
CEL – China Energy Label
China introduced mandatory energy efficiency labeling for
electric motors in June 2008.
From September 1, 2008, and until the transition phase expires,
the affected electric motors may only be imported into China and
sold in the country with a valid "China Energy Label".
The motor must be labeled with the "China Energy Label" sticker,
which states the efficiency class.
In addition to the Energy Label
(dimensions, 80 x 54 mm) the efficiency must also be stamped
on the rating plate.
2, 4 and 6-pole motors with a line frequency of 50 Hz and a
nominal voltage of up to 1000 V must be appropriately marked.
Efficiency classes 2 and 3 apply here to motors with nominal
outputs of 0.75 to 375 kW.
