IP67 Terminal Box 121 - PLA.15.121.107.A (With Rad Shield)

Special variant derived from the standard FS 831/121 model, engineered to provide advanced thermal

and environmental protection along the trackside. The key feature of this version is the integration of a

polycarbonate (PC) solar radiation shield (Rad Shield), mounted directly onto the lid using dedicated screws.

To allow this assembly, the original lid undergoes a structural modification featuring special bushings with

threaded inserts. The entire configuration ensures an IP67 protection rating, safeguarding internal

components against water and dust ingress, as well as overheating caused by direct sunlight exposure.
