The BPG range comprises 16 sizes of enclosure manufactured in glass reinforced polyester or a carbon loaded anti-static GRP (BPGC). The BPG and BPGC enclosures are suitable for use in hazardous areas, specifically ATEX and IECEx Ex ‘e’ (Zone 1 & 2), EEx ‘nA’ (Zone 2) and CSA, UL & FM (Class 1, Div 2).
Under fire test conditions the structure holds together even if the resin is depleted. The BPG range when fitted with ceramic terminals meets the requirements of IEC 331 (750°C for 3 hours) and also BS6387/1983 (950°C for 3 hours – flame only).
The BPG junction box has excellent ingress protection qualities (IP66/67 and Type 4X) due to the enclosure’s labyrinth seal system, whereby the seal is protected from the external environment. The mounting holes, although contained within the profile of the enclosure, are also designed to sit outside the seal maintaining its integrity.
The BPG range has also passed the Shell/ERA deluge test which was devised to adequately test enclosures and electrical equipment which is routinely subjected to ships decks conditions or fire deluge systems.
All external fasteners and fixings are manufactured from 316 grade stainless steel to ensure reliability. The BPG is suitable for operation in ambient temperatures ranging from -65°C to 130°C.
The BPG range is also available carbon loaded (BPGC) which helps to reduce the surface resistance of the material and consequently reduce the risk of spark from static build up.
Earthing can be accomplished by various means. External/internal earth stud which in turn can be connected to the terminal mounting rail or component mounting plate, an earth continuity plate can be fitted around the inner walls to provide continuity for cable glands and various in rail mounted earth terminals or proprietary earth bars can be fitted inside the enclosure.
The BPG range can be supplied fitted with any component approved terminal to apparatus level or can be supplied empty as component approved.
