Serie GJB Explosion-proof boxes made of copper-free Aluminum varies from terminal boxes to enclosure. They are equipped with pillar or strip terminals and assembly plates to distribute electricity in hazardous areas including zone 1, 2, 21 and 22. In addition, big sizes can be equipped with circuit breakers but without external access as a control panel to be able to find the fault more easily.
Cables enter to GJBs via explosion-protected conduit or cable glands and unused drilled holes would be closed with protected stopping plugs.
