£0.61
The TE Connectivity FEM3A 1SNA116576R1500, also referenced as the FEM6.3A end section, is a durable grey terminal block end section designed for compatible ENTRELEC SNA screw-clamp terminal blocks. It provides the insulating end cover required at the open side of selected asymmetric terminal blocks, helping create a safe, neat and professional DIN rail terminal assembly.
Specifically designed for the M4/6.3A terminal block family, the FEM3A is compatible with M4/6.3A, M4/6.3A.NC and M4/6.3A.P configurations. Its purpose-matched profile closes the exposed side of the terminal assembly while maintaining the compact dimensions and organised appearance expected from the ENTRELEC SNA system.
Manufactured from durable grey polyamide with a UL 94V-0 flammability rating, the FEM3A is suitable for demanding industrial environments. The end section has a compact 3 mm spacing, weighs approximately 3.3 g and is designed for terminal assemblies mounted on G32, TH35-7.5 and TH35-15 DIN rail systems.
End sections such as the TE Connectivity FEM3A are used to close the exposed side of asymmetric terminal blocks at the end of a DIN rail assembly. Installing the correct end section helps maintain insulation between conductive components and adjacent equipment while giving the completed terminal row a clean and organised finish.
The FEM3A is shaped specifically for compatible M4/6.3A family terminal blocks, ensuring correct alignment with the terminal profile. Its flame-resistant polyamide construction and broad operating temperature range make it suitable for industrial control cabinets, machinery and automation systems where reliable terminal block accessories are required.
