£0.45
The TE Connectivity FED2-4 1SNA399577R0200 is a compact grey end section for DR1.5/4 terminal blocks, designed to provide the required end insulation and separation within industrial terminal assemblies. Part of the established Entrelec SNA terminal block accessory range, it provides a purpose-designed finishing component for compatible DIN-rail terminal installations.
Also identified as FED2-4-E, this accessory has a slim 1 mm spacing and is manufactured to match compatible terminal block profiles. Installing the correct end section helps cover the open side of a terminal assembly, supporting orderly construction and appropriate insulation within control panels, switchgear and automation equipment.
The FED2-4 measures approximately 28 × 1 × 25.9 mm and weighs approximately 1.4 g. Its compact dimensions allow it to integrate neatly with compatible terminal assemblies mounted on common G32 and TH35 DIN-rail systems.
Terminal block end sections are used where the construction of a terminal leaves an exposed side requiring a dedicated insulating cover. Using the matching end section helps complete the terminal assembly while maintaining an organised and professional installation inside electrical control equipment.
With a thickness of only 1 mm, the FED2-4 adds minimal width to a terminal assembly. Its profile is designed for compatible DR1.5/4 terminals, making it a practical accessory for panel builders and automation engineers assembling compact DIN-rail connection systems.
