Effortless Inspections: Terminal Boxes that Makes Inspections Safe and Simple


New GR Series enclosures in glass-fiber reinforced polyester with inspection window and spring-loaded lid

The new GR Series enclosures in glass-fiber reinforced polyester with inspection window and spring-loaded lid make routine inspections of hazardous area equipment simple, cost-effective, and time-saving. The inspection window allows regular maintenance programs to quickly check for water ingress or other corrosion problems in electrical and instrumentation circuits with no need to remove the cover, so corrective action can be taken to reduce the risk of process interruptions or unplanned shutdowns. The GR Series offers protection methods for enhanced safety (Ex e) and intrinsically safe (Ex i) installations.

Undetected potential faults may lead to the entire box, including cable glands, and sometimes local wiring being replaced, which is both costly and time consuming and means that other, proactive maintenance is delayed .

Pepperl+Fuchs offers a solution to simplify such operations to a minimum. The sophisticated viewing windows with protective flap enable easy, cost- and time-efficient maintenance. Customers can choose between 13 sizes to find the best solution for them. 


  • The glass inspection window provides cost-effective and time-saving routine maintenance.
