Circuit Protection for Class I, Division 2 Applications
Several options are available to deploy an automation control system in a hazardous environment. In the past, NEMA 7 Explosion Proof Enclosures were predominately used to install the electrical controls. These enclosures are designed to prevent any arcing or flame from a component failure inside the enclosure to the outside volatile process area.
Today, a NEMA 4/4X industrial enclosure is commonly utilized with an Air Purge System. These systems exchange the air from inside the enclosure with fresh air processed through the purge system - minimizing high concentration levels of hazardous gases in the enclosure which could cause an explosion with an arcing component, such as electrical relays, switches, fuses, circuit breakers, etc.
As a replacement to both of these options, E-T-A offers a line of circuit protection devices for Class I, Division 2, Hazardous location applications. These products are an alternative for protecting 24 VDC field devices in a hazardous location because as long as all the components installed in an electrical control enclosure have a Class I, Div. 2, approval, the NEMA 7 enclosure and/or Purge System are no longer needed to meet most application specifications.
