Explosion-proof junction box EJB-A

Explosion-proof junction box EJB-A

The EJB series explosion-proof junction boxes are suitable for installation in all areas of the plant at risk of explosion and/or zones 1, 2, 21, 22. The quality of this product is known worldwide due to its aluminum alloy and mechanical properties. EJB junction box is mainly used as a box for carrying bollard and rebar assembly, fuse holder, transformer, reactor, for producing control and signal cards, lighting and power cards, satellites and motor output boxes of various types.

The materials used in the construction of EJB A explosion-proof junction boxes have been studied to provide maximum protection against highly corrosive agents found in hazardous industries:

• Body and cover made of aluminum alloy without copper (less than 0.1%)
• External epoxy powder coating RAL 7001
• Anti-condensation inner cover (on request)
• AISI 316 stainless steel anti-loosen bolts and earth bolts
• silicone cover gasket
• Self-leveling silicone heat-resistant glass window
