CTB III stainless steel enclosures – 300 x 300 x 245mm (HxWxD)

  • The 1/4 turn lock or the retained stainless steel slotted hex bolt fastenings provide a rapid means of achieving high integrity ingress protection (IP66/67) for reliable & rapid environmental protection.
  • The EPDM is a sealing gasket for excellent ingress protection IP66/67 with good recovery and re-sealing properties.
  • A special designed flat surface integral drainage channel prevents liquids or other solids contaminates from running in or falling into the enclosure when the door is opened. This design also prevents gasket from becoming broken when the door is tight closed.
  • The enclosure is mounted by two or four horizontal 3mm thick heavy-duty surface welded stainless steel lugs. These provide a rapid, secure and reliable means of enclosure installation.
