Why the W Exec?

W Exec Zone 2 BENEFITS

Multi-Mount

The unique Flexi-Mount design allows the terminal box to be positioned on the top, left or right by simply adjusting the feet.

Foot-mounted motors can also be converted to flange-mounted configurations from stock, reducing modification lead times and simplifying installation.

Direct Replacements

Modern W Ex ec motors provide an up-to-date replacement for older W Ex nA motors, simplifying upgrades and replacements.

We can identify the correct replacement from your existing motor nameplate.

Frequently Asked Questions

EEx nA, Ex nA and Ex ec all refer to non-sparking motors designed for use in Zone 2 hazardous areas, but they reflect the evolution of explosion protection standards over time. EEx nA is the original European marking, Ex nA is the later harmonised IEC/ATEX designation, and Ex ec is the current certification under the latest IEC 60079 standards. As a result, new Zone 2 motors are now typically supplied with Ex ec certification, making them the modern replacement for older EEx nA and Ex nA motors.
