Worldwide Standards Overview
Why is important to know and understand local efficiency regulations?
 Understand OEMs and end customers needs;
 Be a technical reference about efficiency regulations and get
customer’s trustworthy by giving correct support;
 Avoid non compliance efficiency level on the end of the sales process;
 Find the optimal point between stock volume and motor flexibility;
 Be aware and ready to react during shifting of efficiency levels having
the right motors in stock and avoiding stock of outdated motors.

Labeling Middle East
Efficiency Level

Most of Middle East countries
do not have a minimum
efficiency requirement.

Cyprus, Israel and Turkey are
the exceptions, adopting the
same requirement as Europe
(IEC IE2).

Saudi Arabia is studying also
adopting IEC IE2.
Although IEC is generally
adopted, for some specific
projects NEMA efficiency
levels may be required.
Requirements (only for Cyprus, Israel and Turkey)
Nameplate shall record :

Efficiency level (IE2/IE3)

Efficiency values for 50, 75 and 100% load

