- Ex d
The enclosure withstands a defined internal explosion and limits transmission outside. Its entries and joints belong to that assessed assembly.
- Flamepath
A specified joint allows hot gases to cool along the path. Gap, length, surface and damage limits come from the applicable equipment requirements.
- Explosion-proof cable glandThis term
Select the gland by its actual protection concept, cable construction and certificate conditions. The trade name alone does not determine suitability.
- Stopping plug
The closure must suit the equipment entry and protection concept. Check the certificate, usable threads and any required seal.
A flameproof enclosure withstands a specified internal explosion and controls its joints. A cable entry and an unused-entry closure each need the permitted protection concept and mounting arrangement.
Conceptual flameproof interfaces with exaggerated joint gaps. No flamepath dimension, thread count, pressure capability or equipment certification is represented.
