FAQ

What does “63 A” mean?

It refers to the maximum continuous current rating the plug is designed to safely carry — suitable for medium-to-high power industrial connections. 

What is the significance of ATEX and IECEx certification?

These certifications indicate that the plug is tested and approved for use in hazardous (explosive) atmospheres including gas and dust environments. 

Why is IP66 important?

An IP66 rating means the plug is completely protected against dust ingress and can withstand powerful jets of water, making it ideal for industrial outdoor and indoor use. 

Can the plug be used with standard industrial sockets?

While it can mate with standard industrial sockets of matching type/specification, its main advantage is compatibility with explosion-proof systems in hazardous locations.
