Field junction box 
Model : B500 series

Service intended

The Field junction box range of enclosures delivers an outstanding performance in the severest conditions and meet the needs of the increasingly stringent requirements of hazardous area applications that can be found in particular in the process and energy industries. Therefore, B500 Series is explosion proof type product which is designed to be used in a critical danger zone by acquiring IECEx and ATEX certificate.
