The TE Connectivity ENTRELEC ES4 1SNK505910R0000 is a dark-grey end section cover / end plate from the SNK Series, designed for use with compatible screw clamp terminal blocks. Installed at the end of a terminal block assembly, it provides an insulating barrier and a neat, finished profile for professional DIN rail installations.
Manufactured from durable polyamide, the ES4 is designed to complement ENTRELEC SNK screw clamp terminal assemblies used in industrial control panels, machinery and electrical distribution systems. Its dark-grey colour provides a neutral finish that integrates cleanly with terminal blocks of different colours while helping define the end of an assembled terminal row.
The ES4 measures 50.9 mm high × 33.7 mm deep with a compact 2.2 mm product spacing and weighs approximately 2.2 g. It is rated for operation from -55 to +110 °C, provides IP20 protection and uses material rated to UL 94V-0 for demanding industrial environments.
End plates are important accessories in modular terminal block systems because the open side of certain terminal blocks requires a suitable insulating cover at the end of an assembled row. A correctly matched end section cover helps create a finished terminal assembly while maintaining separation from neighbouring components.
The ENTRELEC ES4 is designed specifically for compatible SNK Series screw clamp terminal blocks. Its slim 2.2 mm profile adds minimal width to the terminal assembly, while its polyamide construction, broad operating temperature range and UL 94V-0 classification make it suitable for professional control panel and machinery applications.
