New Regulation on Semiconductor Controllers

The Secretary of Economy has announced in the official journal on October 23, 2017, the regulation NMX-J-538-4-2-ANCE-2017. This Mexican Standard pertains to semiconductor controllers and starters for alternating current motors. It applies to both devices that may include a series of mechanical switching components and those that do not, intended for connection to circuits with an assigned voltage not exceeding 1,000 V in alternating current.

International Equivalent

The international equivalent standard is the IEC 60947-4-2, which focuses on low-voltage switchgear and control gear, specifically Part 4-2: Contactors and motor-starters AC semiconductor motor controllers and starters, ed3.0 (2011-05), with certain modifications.

Effective Date

This standard will take effect on December 21, 2017.
