Details: EJBX*


The enclosure series EJBX forms the optimal basis for the application-specific configuration of terminal boxes, control stations as well as control and distribution panels.

The enclosures are certified Ex d IIB+H2 and Ex tb as well as "explosion-proof". They are available in many sizes, a wide range of operating elements and monitoring functions can be integrated. They are manufactured from high-quality stainless steel.

This durability as well as the flexible customization options cover the requirements of many industries including offshore and marine applications. A choice of windows allows viewing of integrated monitoring functions. Electrical components can be integrated as per customer specification.
